* fix(usage-bar): bound template file cache to prevent unbounded watcher growth
Add MAX_CACHED_TEMPLATE_FILES=64 limit; evict the oldest entry (closing
its fs.watch watcher) before allocating a watcher for a new key when
the cache is full.
Eviction runs before watcher allocation so we never create a watcher
only to close it immediately. Eviction triggers only when inserting a
new key (!fileCache.has(path)) — retries for an existing key must
not evict other entries.
