Implements the full signal detection pipeline: Backend: - app/services/lemmy/client.py: async Lemmy API v3 client, community@instance addressing, integer cursor dedup, normalised post dicts - app/services/scraper.py: platform-agnostic scraper; Reddit (.json API, fullname cursor) + Lemmy (integer ID cursor); keyword/regex/all match modes, min_score gate, NormalizedPost shape, upsert dedup via UNIQUE post_id - app/api/endpoints/signals.py: CRUD for signal_rules + signals queue; POST /signals/scrape manual trigger; scrape-state viewer - migrations 010-012: signal_rules, signals, signal_scrape_state tables - scheduler: interval job every 30 min (scraper_enabled=True in config) - Fixed migration collision: 007_signal_rules.sql → 010, 008 → 011, 009 → 012 Frontend: - SignalsView.vue: signal feed with status filter (new/saved/dismissed), keyword chips, score/comment counts, save/dismiss actions, rules editor panel - api.ts: SignalRule, Signal types + signalRules/signals API methods - Nav: Signals as default landing route (replaces /campaigns default) Closes #7 (signal extraction), closes #10 (Lemmy JSON crawler)
