feat: Phase 5 — filtres, actions Ntfy, outgoing webhooks, state file

- Filtres avancés: drop, set_priority, add_tag avec wildcard * (filter_outgoing.v)
- Notifications structurées: click_url + actions (ntfy.v + sources/event.v)
- Webhook sortant: Slack, Discord, JSON (filter_outgoing.v)
- Fichier d'état: persistance poll_state + silence_until (filter_outgoing.v)
- Config: sections filters, outgoing, state (config.v)
- Tests: 9 nouveaux tests unitaires (filter_outgoing_test.v)
- Docs: ROADMAP Phase 5 4/8, version 0.5.0
