/**
 * Sync Module
 *
 * Provides synchronization functionality for keeping the code graph
 * up-to-date with file system changes.
 *
 * Components:
 * - FileWatcher: Debounced fs.watch that auto-triggers sync on file changes
 * - Watch policy: decides when the watcher must be disabled (e.g. WSL2 /mnt)
 * - Git sync hooks: opt-in commit/merge/checkout hooks when watching is off
 * - Git worktree awareness: detect when a query borrows another tree's index
 * - Content hashing for change detection (in extraction module)
 * - Incremental reindexing (in extraction module)
