fix(watcher.node): Normalize paths and improve Node watcher robustness: restart/rescan on errors (including ENOSPC), clear stale state, and remove legacy throttler

@@ -80,11 +80,20 @@ The Node.js watcher has been refactored with elegant patterns inspired by [choki
 - Encapsulates file tracking and inode management
 - `dispose()` method freezes object to catch use-after-cleanup bugs
 
-**Throttler Pattern:**
-- More sophisticated than simple debounce
-- Tracks count of suppressed events
-- Returns `false` if already throttled, `Throttler` object otherwise
-- Used for change events to prevent duplicate emissions
+**Path Normalization (v6.3.1+):**
+- ALL paths are normalized to absolute at entry points
+- Prevents relative/absolute path mismatch bugs
+- `watchPath()`, `handleFsEvent()`, `scanDirectory()` all resolve paths
+
+**Restart Rescan (v6.3.1+):**
+- When watcher restarts, it rescans the directory
+- Catches files created during the restart window
+- Clears stale DirEntry data before rescan
+- Clears pending unlink timeouts to prevent stale events
+
+**ENOSPC Handling (v6.3.1+):**
+- inotify limit errors now trigger watcher restart
+- Previously only logged error without recovery
 
 **Atomic Write Handling:**
 - Unlink events are queued with 100ms delay
