Everything an agent can do with moments, a person can now see and change
in the app.
- Rule editor: a moment picker beside the trigger. Catalog moments are
ticked; a named procedure's `skill.<name>` is typed and checked as the
server checks it. `moments` is always sent, so unticking the last moment
unmounts the rule.
- Settings, Moments section (General tab): for each moment, what it
means, the actions that reach it on this install (shipped ones can be
switched off, the install's own removed), how many rules are mounted on
it, and deliveries and agent opens over the window. Below that: named
procedures with mounts, switched-off defaults with Restore, and a form to
add an action.
- retrieval_telemetry.moment_usage: per moment, `delivered`, `rules`,
`opened` (agent pulls after the first delivery there; an upper bound, as
by_source is) and `last_delivered_at`. No ratio, because a mount is a
person's statement, not a ranker's guess. Guarded on its own, and also
reported in retrieval_summary as `moment_usage`.
- rulebooks.mount_counts; mounted_moments now derives from it.
- GET /api/retrieval/moments carries `mounted` and `usage` (?days=).
DELETE /moments/mappings also reads the mapping from query parameters,
since the browser's DELETE sends no body.
