Phase 2: API Unification & Typed Results + Phase 2.1 Fixes

Phase 2 - Breaking Changes (v2.0.0):
- Added typed result interfaces (FileMetadata, DirectoryMetadata, VaultInfo, SearchResult, SearchMatch)
- Unified parameter naming: list_notes now uses 'path' parameter (removed 'folder')
- Enhanced tool responses with structured JSON for all tools
- list_notes: Returns array of FileMetadata/DirectoryMetadata with full metadata
- search_notes: Returns SearchResult with line numbers, snippets, and match ranges
- get_vault_info: Returns VaultInfo with comprehensive statistics
- Updated all tool descriptions to document structured responses
- Version bumped to 2.0.0 (breaking changes)

Phase 2.1 - Post-Testing Fixes:
- Fixed root listing to exclude vault root folder itself (handles path '', '/', and isRoot())
- Fixed alphabetical sorting to be case-insensitive for stable ordering
- Improved directory metadata with better timestamp detection and error handling
- Fixed parent folder validation order (check if file before checking existence)
- Updated documentation with root path examples and leading slash warnings
- Added comprehensive test suite for sorting and root listing behavior
- Fixed test mocks to use proper TFile/TFolder instances

Tests: All 64 tests passing
Build: Successful, no errors
