notes: private Obsidian vault tracker at /trackers/notes

Vault files stay the source of truth (bind-mounted read-write at /notes):
atomic writes chowned to the vault owner, hash-checked saves (409 on a
newer file), deletes to .trash. notes.* is a full-text/link index kept
current by a recursive watcher plus a 60s rescan; live updates over the
owner-only /ws/notes channel (paths and hashes only). Wikilinks, embeds,
backlinks, tags, callouts, image paste. Owner-only everywhere (404).
