Config caches, the profile re-scan watcher, the MCP reconciler, managed-scope
reads, the completer memo, OAuth heal marks, and the skill-manifest snapshot
keyed change detection on (st_mtime_ns, st_size) only, so a replacement that
preserved both (cp -p, rsync -t, timestamp-pinning scripts, sync clients) was
treated as unchanged and stale values were served until restart.
Add st_ino (fresh inode on atomic replace) and st_ctime_ns (cannot be
backdated via os.utime) to every signature via a shared
hermes_cli.managed_scope.file_signature() helper.
Fixes#111105
