Closes #29

Part of the server monitoring plan (phase 2.1). Stacked on #32 (base feat/28-sources-json-dedup).

Changes

Trigger.STALE ("Source muette", default severity alert), in the new PERIODIC_TRIGGERS set (never evaluated on upload).
Expected period: rule param after (validated duration, stored in seconds) or else the stream's latest report expect_every. No period → never silent.
engine.check_stale(): for each enabled stale rule, the latest DONE report of every matching stream (ref, type, custom name, variant); silent when now - max(uploaded_at, last_seen_at) > period + max(10 min, 10 %). State tracked in EventRuleState.active: one alert on the edge, then one info event ("de nouveau active") when the stream reports again. _raise gained an optional severity override for that.
Celery beat: apps.events.tasks.check_stale_sources every 5 minutes, seeded on post_migrate (IntervalSchedule).
Argus's own daily self-reports (sweep-closed-prs, prune-history) now announce expect_every: 1d.
README, feature catalog; tests in apps/events/test_stale.py.

Closes #29 Part of the server monitoring plan (phase 2.1). **Stacked on #32** (base `feat/28-sources-json-dedup`). ## Changes - `Trigger.STALE` ("Source muette", default severity alert), in the new `PERIODIC_TRIGGERS` set (never evaluated on upload). - Expected period: rule param `after` (validated duration, stored in seconds) or else the stream's latest report `expect_every`. No period → never silent. - `engine.check_stale()`: for each enabled stale rule, the latest DONE report of every matching stream (ref, type, custom name, variant); silent when `now - max(uploaded_at, last_seen_at) > period + max(10 min, 10 %)`. State tracked in `EventRuleState.active`: one alert on the edge, then one **info** event ("de nouveau active") when the stream reports again. `_raise` gained an optional `severity` override for that. - Celery beat: `apps.events.tasks.check_stale_sources` every 5 minutes, seeded on `post_migrate` (IntervalSchedule). - Argus's own daily self-reports (`sweep-closed-prs`, `prune-history`) now announce `expect_every: 1d`. - README, feature catalog; tests in `apps/events/test_stale.py`. ## Checks pytest (215 passed), pylint 10/10, autopep8, bandit clean. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_014BSmBtGWeFBD9z4mYm9SjA

- New periodic trigger `stale`: the expected period is the report's
  expect_every, or the rule's own `after` delay; streams with neither
  are ignored. Silent past period + max(10 min, 10 %) raises the event
  once, and an info "de nouveau active" event when the stream reports
  again (last_seen_at of de-duplicated reports counts).
- Celery beat task check_stale_sources every 5 minutes, seeded like
  the reports app's periodic tasks.
- Argus's own daily self-reports announce expect_every: 1d.

Closes #29
