feat(phase6a): behavioral insight pipeline ingestion + tagging + compression
- prisma: sessions_meta, compressed_sessions, ingestion_watermarks
- worker: PostHog client (eu.i.posthog.com), heuristic filter
- worker: BullMQ insight-pipeline queue (ingest 5min / tag 2min / compress 3min)
- worker: tagger (bug_suspected, ux_friction, upgrade_hesitation, etc.) + severity scoring
- worker: rrweb -> semantic timeline transform + 8-pattern PII sanitization
- worker: fingerprint hash + MinIO upload (bucket: insight-compressed)
- web: /insights pipeline dashboard + session timeline viewer
- sidebar: Insights nav entry
LLM (Phase 6b), insight inbox, cost dashboard, GitHub loop deferred to later phases.
