* refactor: centralize file watching with single fsnotify.Watcher

Refactored the LSP watcher system to use a single shared fsnotify.Watcher
instance instead of one per LSP client, eliminating all file watching
duplication and significantly improving resource efficiency.

Key changes:
- Added GlobalWatcher singleton managing single fsnotify.Watcher
- Centralized all file system event processing and distribution
- Eliminated duplicate directory and file watching across clients
- Implemented global debouncing with per-client event filtering
- Maintained full backward compatibility with existing LSP integration

Benefits:
- Single watcher instance regardless of LSP client count
- Each directory/file watched exactly once
- Centralized event processing eliminates duplicate operations
- Significant reduction in file descriptors and memory usage
- Linear resource growth with unique files, not client count

* docs: clarify directory-only watching strategy

Enhanced documentation and comments to clearly explain that the file
watcher implementation only watches directories, not individual files.
This approach is more efficient as fsnotify automatically provides
events for all files within watched directories.

Key clarifications:
- Added comprehensive documentation explaining directory-only approach
- Clarified that fsnotify automatically covers files in watched directories
- Enhanced comments explaining new directory detection and handling
- Added test to verify only directories are watched, never individual files
- Improved code organization and readability

Benefits of directory-only watching:
- Significantly fewer file descriptors used
- Automatic coverage of new files created in watched directories
- Better performance with large codebases
- Simplified deduplication logic

* refactor: remove unnecessary directory tracking, rely on fsnotify deduplication

Simplified the GlobalWatcher by removing manual directory tracking since
fsnotify handles deduplication internally. According to fsnotify docs:
"A path can only be watched once; watching it more than once is a no-op"

Key improvements:
- Removed watchedDirs map and associated mutex (no longer needed)
- Simplified addDirectoryToWatcher method to directly call fsnotify
- Updated tests to verify fsnotify deduplication behavior
- Reduced memory usage and code complexity
- Maintained all functionality while relying on fsnotify's built-in deduplication

Benefits:
- Less memory usage (no directory tracking map)
- Simpler code with fewer mutexes and less complexity
- Relies on well-tested fsnotify deduplication instead of custom logic
- Better performance due to reduced synchronization overhead

* refactor: remove workspace path tracking, embrace full idempotency

Removed unnecessary workspace path tracking since directory walking
and fsnotify.Add() calls are idempotent. Multiple WatchWorkspace calls
with the same path are now safe and simple.

Key improvements:
- Removed workspacePaths map and workspacesMu mutex
- Simplified WatchWorkspace to be fully idempotent
- Reduced GlobalWatcher struct size and complexity
- Updated tests to verify idempotent behavior instead of deduplication
- Embraced "simple and idempotent" over "complex and optimized"

Benefits:
- Even less memory usage (no workspace tracking)
- Simpler code with fewer mutexes (down to 2 from original 4)
- Fully idempotent operations - safe to call multiple times
- Better maintainability with less state to manage
- Relies entirely on fsnotify's proven deduplication

Philosophy: Let fsnotify handle what it's designed to handle, keep our
code simple and idempotent rather than trying to micro-optimize.

* refactor: remove redundant file type validation in file opening

Removed duplicate file extension checking since HandlesFile() already
validates that the LSP client handles the file type. This eliminates
redundant hardcoded extension checks and potential inconsistencies.

Key improvements:
- Removed shouldOpen extension validation logic
- Simplified file opening to trust HandlesFile() validation
- Eliminated hardcoded extension lists that could become stale
- Reduced code duplication between global_watcher.go and watcher.go
- More consistent behavior across different file opening paths

Benefits:
- Single source of truth for file type handling (LSP client config)
- Less code to maintain and keep in sync
- More flexible - supports any file types configured for LSP clients
- Eliminates potential bugs from hardcoded extension mismatches
- Cleaner, more maintainable code

The file type validation now happens exactly once at the right place:
when checking if a client HandlesFile(), not again during file opening.

* feat: add hierarchical .gitignore/.crushignore support to LSP file watcher

Implements proper hierarchical ignore file support that checks for .gitignore
and .crushignore files in each directory from the target path up to the
workspace root, following Git's ignore semantics.

Key improvements:
- Hierarchical ignore checking: walks directory tree from workspace root to target
- Supports both .gitignore and .crushignore patterns
- Handles trailing slash patterns correctly (e.g., "node_modules/" matches directories)
- Uses go-gitignore library for proper pattern matching
- Maintains workspace root tracking for multi-workspace support
- Comprehensive test coverage for ignore functionality

This ensures the LSP file watcher respects ignore patterns at all directory
levels, not just the workspace root, providing consistent behavior with Git
and other tools that support hierarchical ignore files.

* chore: small improvement

* refactor: simplify global watcher to single workspace

Remove multi-workspace concept that was never used in practice.
All LSP clients watch the same single workspace directory, so the
complexity of tracking multiple workspace roots was unnecessary.

Changes:
- Replace workspaceRoots map with single workspaceRoot string
- Remove unnecessary mutex protection (workspace set once at startup)
- Simplify shouldIgnoreDirectory logic
- Update tests to match simplified structure

* refactor: major simplification of file watcher logic

Remove unnecessary complexity and consolidate duplicate code:

- Remove unnecessary watcherMu mutex (watcher set once at init)
- Consolidate duplicate file opening logic between GlobalWatcher and WorkspaceWatcher
- Simplify AddRegistrations by removing complex workspace scanning
- Replace custom glob matching with proven doublestar library
- Remove unused shouldExcludeDir function
- Streamline file preloading to only handle high-priority files

Benefits:
- ~200 lines of code removed
- Better reliability using doublestar for pattern matching
- Improved performance with event-driven approach vs bulk scanning
- Single source of truth for file operations
- Reduced memory usage and fewer goroutines
