ci: upgrade to Node.js 20 for native globalThis.crypto support

This commit resolves all required and optional issues from the plugin
submission review to comply with Obsidian plugin guidelines.

Required Changes:
- Type Safety: Added eslint-disable comments with justifications for
  necessary any types in JSON-RPC tool argument handling
- Command IDs: Removed redundant "mcp-server" prefix from command
  identifiers (BREAKING CHANGE):
  - start-mcp-server → start-server
  - stop-mcp-server → stop-server
  - restart-mcp-server → restart-server
- Promise Handling: Added void operator for intentional fire-and-forget
  promise in notification queue processing
- ESLint Directives: Added descriptive explanations to all
  eslint-disable comments
- Switch Statement Scope: Wrapped case blocks in braces to fix lexical
  declaration warnings in glob pattern matcher
- Regular Expression: Added eslint-disable comment for control character
  validation in Windows path checking
- Type Definitions: Changed empty object type {} to object in MCP
  capabilities interface
- Import Statements: Added comprehensive justifications for require()
  usage in Electron/Node.js modules (synchronous access required)

Optional Improvements:
- Code Cleanup: Removed unused imports (MCPPluginSettings, TFile,
  VaultInfo)

Documentation:
- Enhanced inline code documentation for ESLint suppressions and
  require() statements
- Added detailed rationale for synchronous module loading requirements
  in Obsidian plugin context
- Updated CHANGELOG.md for version 1.1.2

All changes verified:
- Build: Successful with no TypeScript errors
- Tests: All 760 tests passing
- ESLint: All review-required issues resolved

Version bumped to 1.1.2 in package.json and manifest.json

+## [1.1.3] - 2025-12-16
+
+### Fixed
+- **Sentence Case**: Fixed remaining UI text violations
+  - `main.ts`: "Toggle MCP Server" → "Toggle MCP server"
+  - `settings.ts`: "Authentication & Configuration" → "Authentication & configuration"
+  - `settings.ts`: "UI Notifications" → "UI notifications"
+
+- **Promise Handling**: Improved async/promise patterns per Obsidian guidelines
+  - `main.ts`: Changed `async onunload()` to synchronous with `void this.stopServer()`
+  - `routes.ts`: Wrapped async Express handler with void IIFE pattern
+  - `mcp-server.ts`: Promise rejection now always uses Error instance
+
+- **Async/Await Cleanup**: Removed `async` from 7 methods that contained no `await`:
+  - `mcp-server.ts`: `handleInitialize`, `handleListTools`
+  - `vault-tools.ts`: `getVaultInfo`, `listNotes`, `createFileMetadataWithFrontmatter`, `exists`, `resolveWikilink`
+  - `link-utils.ts`: `validateLinks`
+
+- **Type Safety**: Replaced `any` types with `Record<string, unknown>` and removed eslint-disable directives
+  - `mcp-server.ts`: Tool arguments type
+  - `tools/index.ts`: `callTool` args parameter
+  - `notifications.ts`: `args` interface field, `showToolCall` parameter, `formatArgs` parameter
+
+- **Import Statements**: Eliminated forbidden `require()` imports
+  - `crypto-adapter.ts`: Replaced `require('crypto')` with `globalThis.crypto`
+  - `encryption-utils.ts`: Replaced bare `require('electron')` with `window.require` pattern
+
+### Changed
+- Updated test mocks to match new synchronous method signatures and import patterns
+
+---
+
+## [1.1.2] - 2025-11-15

+  - **Command IDs**: Removed redundant plugin name prefix from command identifiers (BREAKING CHANGE):
+    - `start-mcp-server` → `start-server`
+    - `stop-mcp-server` → `stop-server`
+    - `restart-mcp-server` → `restart-server`
+  - **Promise Handling**: Added `void` operator for intentional fire-and-forget promise in notification queue processing

+# Obsidian Plugin Code Review Fixes Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Fix all required issues from the Nov 16, 2025 ObsidianReviewBot code review to unblock plugin submission approval.
+
+**Architecture:** Systematic file-by-file fixes addressing: sentence case UI text, async/await cleanup, eslint directive removal, require() to ES6 import conversion, and promise handling improvements.
+
+**Tech Stack:** TypeScript, Obsidian API, ESLint
+
+---

+        res.status(500).json(createErrorResponse(null, ErrorCodes.InternalError, 'Internal server error'));
+    }
+});
+```
+
+To:
+```typescript

+git commit -m "fix: remove eslint-disable directive in tools/index.ts"
+```
+
+---
+
+## Task 6: Fix vault-tools.ts Async Methods
+
+**Files:**
+- Modify: `src/tools/vault-tools.ts:18,63,310,498,925`
+
+**Step 1: Remove async from getVaultInfo (line 18)**
+
+Change from:

+```
+
+To:
+```typescript
+getVaultInfo(): CallToolResult {
+```
+

+```
+
+**Step 6: Update callers if any use await on these methods**
+
+Search for any `await this.getVaultInfo()`, `await this.listNotes()`, `await this.exists()`, `await this.resolveWikilink()`, `await this.createFileMetadataWithFrontmatter()` and remove the `await` keyword.
+
+**Step 7: Verify build**

+
+## Task 7: Fix notifications.ts ESLint Directives
+
+**Files:**
+- Modify: `src/ui/notifications.ts:10-11,78-79,145-146,179`
+
+**Step 1: Fix interface args type (lines 10-11)**
+
+Change from:
+```typescript
+// eslint-disable-next-line @typescript-eslint/no-explicit-any -- Tool arguments come from JSON-RPC and can be any valid JSON structure

+
+## Task 8: Fix crypto-adapter.ts Require Import
+
+**Files:**
+- Modify: `src/utils/crypto-adapter.ts:18-34`
+
+**Step 1: Replace require with dynamic approach**
+
+The challenge here is that require() is used for synchronous access. We need to restructure to use a lazy initialization pattern.
+
+Change the entire Node.js section from:
+```typescript
+// Node.js environment (15+) - uses Web Crypto API standard
+if (typeof global !== 'undefined') {
+    try {
+        // Using require() is necessary for synchronous crypto access in Obsidian desktop plugins
+        // ES6 dynamic imports would create race conditions as crypto must be available synchronously
+        // eslint-disable-next-line @typescript-eslint/no-var-requires -- Synchronous Node.js crypto API access required
+        const nodeCrypto = require('crypto') as typeof import('crypto');
+        if (nodeCrypto?.webcrypto) {
+            return nodeCrypto.webcrypto as unknown as Crypto;
+        }
+    } catch {
+        // Crypto module not available or failed to load
+    }
+}
+```
+
+To (using globalThis.crypto which is available in Node 19+ and Electron):
+```typescript
+// Node.js/Electron environment - globalThis.crypto available in modern runtimes
+if (typeof globalThis !== 'undefined' && globalThis.crypto) {
+    return globalThis.crypto;
+}
+```
+
+**Step 2: Verify build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 3: Commit**
+
+```bash
+git add src/utils/crypto-adapter.ts
+git commit -m "fix: use globalThis.crypto instead of require('crypto')"
+```
+
+---
+
+## Task 9: Fix encryption-utils.ts Require Import
+
+**Files:**
+- Modify: `src/utils/encryption-utils.ts:8-18`
+
+**Step 1: Restructure electron import**
+
+Since Electron's safeStorage must be accessed synchronously at module load time, and ES6 dynamic imports are async, we need to use a different approach. In Obsidian plugins running in Electron, we can access electron through the window object.
+
+Change from:
+```typescript
+// Safely import safeStorage - may not be available in all environments
+let safeStorage: ElectronSafeStorage | null = null;
+try {
+    // Using require() is necessary for synchronous access to Electron's safeStorage API in Obsidian desktop plugins
+    // ES6 dynamic imports would create race conditions as this module must be available synchronously
+    // eslint-disable-next-line @typescript-eslint/no-var-requires -- Synchronous Electron API access required for Obsidian plugin
+    const electron = require('electron') as typeof import('electron');
+    safeStorage = electron.safeStorage || null;
+} catch (error) {
+    console.warn('Electron safeStorage not available, API keys will be stored in plaintext');
+}
+```
+
+To:
+```typescript
+// Safely import safeStorage - may not be available in all environments
+let safeStorage: ElectronSafeStorage | null = null;
+try {
+    // Access electron through the global window object in Obsidian's Electron environment
+    // This avoids require() while still getting synchronous access
+    const electronRemote = (window as Window & { require?: (module: string) => typeof import('electron') }).require;
+    if (electronRemote) {
+        const electron = electronRemote('electron');
+        safeStorage = electron.safeStorage || null;
+    }
+} catch {
+    console.warn('Electron safeStorage not available, API keys will be stored in plaintext');
+}
+```
+
+**Step 2: Verify build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 3: Commit**
+
+```bash
+git add src/utils/encryption-utils.ts
+git commit -m "fix: use window.require pattern instead of bare require for electron"
+```
+
+---
+
+## Task 10: Fix link-utils.ts Async Method
+
+**Files:**
+- Modify: `src/utils/link-utils.ts:448`
+
+**Step 1: Remove async from validateLinks**
+
+Change from:
+```typescript
+static async validateLinks(
+    vault: IVaultAdapter,
+    metadata: IMetadataCacheAdapter,
+    content: string,
+    sourcePath: string
+): Promise<LinkValidationResult> {
+```
+
+To:
+```typescript
+static validateLinks(
+    vault: IVaultAdapter,
+    metadata: IMetadataCacheAdapter,
+    content: string,
+    sourcePath: string
+): LinkValidationResult {
+```
+
+**Step 2: Update any callers that await this method**
+
+Search for `await LinkUtils.validateLinks` or `await this.validateLinks` and remove the `await`.
+
+**Step 3: Verify build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 4: Commit**
+
+```bash
+git add src/utils/link-utils.ts
+git commit -m "fix: remove async from validateLinks method"
+```
+
+---
+
+## Task 11: Final Build and Test
+
+**Step 1: Run full build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 2: Run tests**
+
+Run: `npm test`
+Expected: All tests pass
+
+**Step 3: Commit any remaining changes**
+
+```bash
+git status
+# If any uncommitted changes:
+git add -A
+git commit -m "fix: final cleanup for code review issues"
+```
+
+---
+
+## Optional Tasks (if time permits)
+
+### Optional Task A: Fix Unused Error Variables
+
+**Files:**
+- `src/tools/vault-tools.ts:289,359,393,445,715`
+- `src/utils/encryption-utils.ts:16`
+- `src/utils/frontmatter-utils.ts:76,329,358`
+- `src/utils/search-utils.ts:117,326`
+- `src/utils/waypoint-utils.ts:103`
+
+For each occurrence, change `catch (error) {` or `catch (e) {` or `catch (decompressError) {` to just `catch {`.
+
+### Optional Task B: Use FileManager.trashFile()
+
+**Files:**
+- Modify: `src/adapters/vault-adapter.ts:46-48`
+- Modify: `src/adapters/interfaces.ts` (update IVaultAdapter interface)
+
+This requires passing the App or FileManager to the VaultAdapter, which is a larger refactor.
+
