feat(wavex-ops): consolidate quota-gating, reengagement, realtime rejoin & managed-CTA

[aimerdoux]

Single consolidation of feat/skills-sh-listing → main

Folds the 15 net commits from feat/skills-sh-listing into one reviewable change. The branch had drifted well past its original PR (#31, skills.sh scaffold — already merged) and accumulated unrelated ops work. This PR drops the duplicate skills commit and reconciles cleanly with the watchdog scaffold (#40) and Pool B work (#36/#37) already on main.

What's included

Inference / quota safety

• G1 quota pre-flight gates the live agent handoff (claude-quota-preflight)
• G2 quota circuit breaker pauses the fleet on hard ceiling (ops script)
• G1/G2 detect auth-failure, not just quota (the 91% gap)
• inference worker: per-user Realtime channel auto-rejoin + onboarding URL-prefetch
• Pool B per-request audit + provider fallback; null-safe pool-b-health cast

wavex-os-server jobs / routes

• professional reengagement + booking-fulfillment resolver + inbound-quality sampler
• mission-control + reengagement routes; operator-tunable agent model

Connectors / data

• managed-Composio primary CTA in ConnectorsSidebar
• cro.deals seed for the open_deals routine; dev roadmap docs

DB migrations (20260520*, 20260521*, 20260528*): user_event_stream, kpi_history, booking GMV rpc, fulfillment instrumentation, professional_reengagement, inbound_quality, attribution_coverage_view, reengagement_value_metrics. Resolved a 20260528000001 timestamp collision → 000002.

Verification

• ✅ typecheck clean on all 4 touched packages (inference-server, wavex-os-server, composio-shim, paperclip-plugin-wavex)
• ✅ new unit tests pass (reengagement 12/12, claude-quota-preflight)
• ⚠️ 9 pre-existing e2e-onboarding finalize→500 failures are environmental (pglite can't init in sandbox) and reproduce identically on clean main (cbaa5b3) — not introduced here.
