* feat: enhance field suggestions with advanced filtering and smart defaults

This comprehensive enhancement addresses the most requested feature (#337) with:

**New Syntax Features:**
• Case-insensitive deduplication: {{FIELD:status|case-sensitive:false}}
• Custom defaults: {{FIELD:status|default:To Do|default-empty:true}}
• Exclusion filters: {{FIELD:status|exclude-folder:archive|exclude-tag:deprecated}}
• Enhanced file filtering with inclusion/exclusion logic

**Performance & UX:**
• Progress feedback for large vault operations with time estimation
• Smart caching system (5-minute TTL) for improved performance
• Batch processing to prevent UI blocking during file scanning
• Unicode-aware deduplication preserving original case

**API Integration:**
• New fieldSuggestions module in QuickAdd API
• getFieldValues() method with filtering options
• Cache management for performance optimization

**Quality:**
• 148 comprehensive tests across all components
• 100% backward compatible with existing syntax
• Modular architecture with 8 new utility classes
• Handles edge cases and large vaults (10k+ files)

Fixes #337

* refactor: improve memory management and code quality

- Fix regex pattern in FIELD_VAR_REGEX_WITH_FILTERS by removing incorrect pipe character
- Add memory limits to FieldSuggestionCache (100 entries max, 1000 values per field)
- Implement automatic cache cleanup with proper Obsidian interval registration
- Add cache eviction for oldest entries when limit reached
- Improve type safety in completeFormatter with proper array/unknown type handling
- Add error handling for file read operations
- Remove unused ProgressTracker class and tests
- Remove formatDisplayFormatter test (depends on Obsidian, cannot be tested externally)
- Fix import practices by moving FieldSuggestionCache import to top of main.ts
- Add proper cleanup on plugin unload with destroy() method

* test: add comprehensive tests for EnhancedFieldSuggestionFileFilter

- Add 17 test cases covering all filtering scenarios
- Test inclusion filters (folder, tags)
- Test exclusion filters (folders, tags, files)
- Test complex filter combinations
- Test edge cases (missing metadata, empty filters)
- Test normalization (# prefix, path slashes)
- Achieve 100% code coverage for EnhancedFieldSuggestionFileFilter

This addresses the critical testing gap identified in code review.

* refactor: improve error messages in formatter for better debugging

- Add context snippets to all parsing errors showing the problematic syntax
- Improve variable parsing errors to show surrounding text
- Enhance date/time parsing errors with specific format information
- Update date variable errors to show expected format and actual value
- Provide actionable guidance for current file path errors
- Standardize error message format with consistent capitalization

These changes make debugging template syntax errors much easier by
showing users exactly what part of their template is causing issues.

* feat: integrate Dataview API for improved field suggestions

- Add obsidian-dataview as dev dependency
- Create DataviewIntegration utility for querying field values
- Use Dataview API when available for better performance and consistency
- Support all filtering options (folder, tags, exclusions) in Dataview queries
- Fall back to manual parsing when Dataview is unavailable or inline filter is used
- Automatically handles both YAML frontmatter and inline dataview fields

This integration provides users with the same field parsing behavior
they expect from Dataview queries, while maintaining backward compatibility
for users without the Dataview plugin installed.

* fix: handle file objects from Dataview queries in field suggestions

When Dataview returns file objects (with path/embed/type properties) instead of strings, extract the path property to use as the field value. This fixes the issue where Dataview would find many values but only show a few in the suggestions.

* Fix TypeScript build errors

- Remove unused imports to resolve lint errors
- Add global app declaration for backward compatibility
- Fix incorrect app usage in engine and GUI files
- Resolve inferrable types and prefer-const issues
- Build now succeeds with npm run build

* fix(build): remove global app dependency for npm compatibility

Fixes #829

- Remove global app declaration from global.d.ts
- Update all functions and constructors to accept app parameter explicitly
- Fix modal constructors to take app parameter
- Update AI assistant functions to accept app parameter
- Fix utility functions to properly accept app parameter
- Update all function calls to pass app through proper channels
- Eliminate all global app usage in favor of explicit dependency injection

This resolves TypeScript build errors when using npm instead of bun,
and prepares the codebase for future Obsidian versions where global app
will no longer be available.

…'undefined' (#820)

- Modified getVariableValue() to use nullish coalescing operator
- Fixes issue where {{VALUE}} outputs "undefined" when no input provided
- Preserves legitimate values like empty strings, "0", and "false"
- Added comprehensive tests to prevent regression

Fixes #209

- Added support for default values using pipe syntax: {{VALUE:name|default}}
- Default value is used when user provides empty input
- Works seamlessly with suggesters and variable reuse
- Backwards compatible - existing templates continue to work
- Added comprehensive test coverage (16 test cases)
- Updated documentation in FormatSyntax.md
- Updated constants to include new syntax format

This implementation follows the approach from PR #569 but with improved
test coverage, documentation, and edge case handling.

Fixes #663

* feat: enable VDATE reuse with different formats

- Store parsed date as ISO string with @Date: prefix instead of formatted value
- Allow same date variable to be formatted differently on each use
- Single prompt for date input, multiple format outputs
- Backward compatible - existing templates continue to work
- Updated documentation with example

Example usage:
{{VDATE:date,YYYY}}/{{VDATE:date,MM}}/{{VDATE:date,DD}}/note.md
Enter date once, get: 2024/01/15/note.md

This enables common use cases like hierarchical folder structures
and consistent date formatting across templates.

Note: Unit tests could not be added due to Obsidian plugin testing
limitations. Manual testing is required to verify functionality.

Fixes #69

* fix: handle multiple VDATE variables with same name but different formats

- Replace specific match string instead of using regex replacement
- Prevents infinite loop when same variable name is used multiple times
- Fixes issue where only first occurrence was replaced in templates like:
  {{VDATE:date,YYYY}}/{{VDATE:date,MM}}/{{VDATE:date,DD}}
