Add 'gvfs cache' verb to display shared cache info
Shows cache root, git objects path, repo URL, pack file summary (prefetch count/size, other pack count/size, latest prefetch timestamp), and loose object count. Emits a CacheInfo telemetry event with all stats. Assisted-by: Claude Opus 4.6 Signed-off-by: Tyrie Vella <tyrielv@gmail.com>
