feat: Phase 8 - Write Operations & Concurrency

Browse Source 
Implement safe write operations with concurrency control, partial updates,
conflict resolution, and file rename/move with automatic link updates.

New Tools:
- update_frontmatter: Partial frontmatter updates with concurrency control
- update_sections: Line-based section edits to reduce race conditions
- rename_file: File rename/move with automatic wikilink updates

Enhanced Tools:
- create_note: Added onConflict strategies (error, overwrite, rename)
- delete_note: Added soft delete, dryRun, and concurrency control

Key Features:
- ETag-based optimistic locking via ifMatch parameter
- Version tracking on all write operations
- Conflict resolution strategies
- Link integrity maintenance during file operations
- Safe operations with preview and recovery options

Files Created:
- src/utils/version-utils.ts

Files Modified:

- src/utils/frontmatter-utils.ts
- src/tools/index.ts
- src/types/mcp-types.ts

**Files Modified:**
- `src/tools/note-tools.ts` - Added update_frontmatter, update_sections, renameFile methods; enhanced createNote and deleteNote
- `src/utils/frontmatter-utils.ts` - Added serializeFrontmatter method
- `src/tools/index.ts` - Added new tool definitions and updated callTool method
- `src/types/mcp-types.ts` - Added Phase 8 types (ConflictStrategy, SectionEdit, result types)
**New Tools:**
- ✅ `update_frontmatter` - Partial frontmatter updates with concurrency control
- ✅ `update_sections` - Line-based section edits
- ✅ `rename_file` - File rename/move with automatic link updates
**Enhanced Tools:**
- ✅ `create_note` - Added onConflict strategies (error, overwrite, rename) and version info
- ✅ `delete_note` - Added soft delete, dryRun, and concurrency control
**Key Features:**
- **Concurrency Control**: ETag-based optimistic locking via ifMatch parameter
- **Conflict Resolution**: Three strategies for handling file conflicts
- **Link Integrity**: Automatic wikilink updates when renaming/moving files
- **Safe Operations**: Soft delete (trash) and dry-run preview
- **Partial Updates**: Update frontmatter or sections without full file overwrites
- **Version Tracking**: All write operations return versionId for subsequent operations
**Benefits:**
- Reduced race conditions in concurrent editing scenarios
- Safer file operations with preview and recovery options
- Maintained vault link integrity during reorganization
- Fine-grained control over file modifications
- Better error handling and conflict resolution
