feat(worker): add production runtime

[SuPuHe]

Summary

Adds a runnable production worker process for durable OneShot settlement and recovery.

Scope and acceptance criteria

• Production worker entry point with startup migration, restart recovery, continuous PostgreSQL outbox polling, health/readiness, and graceful shutdown.
• Real Privy Node signing, Arc receipt observation, Subgraph MCP discovery, and Vertex advisory recovery wired fail-closed.
• Outbox jobs are marked DELIVERED only after handler success; failures remain retryable.
• Dedicated Dockerfile.worker, worker scripts, and documented environment contract.
• Provider/configuration/rollback/restart and API-to-worker replay tests added.
• No secrets, generated browser artifacts, unrelated changes, or weakened checks.

Product and security invariants

• Tenant isolation remains fail-closed.
• Sponsor authorization, auditability, and daily caps remain enforced where applicable.
• Recipients cannot modify sponsor controls or access sponsor-only data.
• No secret, token, production identifier, or personal data is committed or pasted into review prompts.
• Settlement remains testnet-only and UNKNOWN never grants blind retry authority.

Invariant notes:

Privy policy identity is re-observed, Arc receipts are identity-bound, Graph and Vertex remain candidate/advisory only, and settlement permission is never inferred from external-index absence or delay.

Validation

Commands and results:

pnpm test: PASS (60 files, 911 tests)
pnpm build: PASS
pnpm lint: PASS
pnpm typecheck: PASS
pnpm check:generated: PASS
pnpm validate:fixtures: PASS
pnpm --filter @oneshot/worker typecheck: PASS
pnpm --filter @oneshot/worker test: PASS (32 tests)
pnpm --filter @oneshot/storage-postgres test: PASS (8 tests)
PostgreSQL/Testcontainers integration: NOT VERIFIED locally; Docker is unavailable on the development host.

The first CI run exposed a 500 in the production-runtime E2E because its API-side IntentLedger was missing required now and nextAttemptId dependencies. Commit da65a162308c2652807672f32919c7fe431876fc supplies deterministic dependencies; the test still asserts create 202, COMMITTED, replay 200, and exactly one submission.

• Reviewer tool/model: free-pi-cli / glm-5.3-flash

• Verdict: VERDICT: PASS

• Findings/residual risks: Testcontainers E2E and Docker image build require a container-capable environment; worker test sources are outside the current tsc project.

• The current committed tree equals the Gate A reviewed tree.

Gate B — exact remote PR head

• Reviewer tool/model: pending

• Verdict: pending

• Findings or residual risks: pending

• Gate B reviewed the current remote head and matches Gate A's approved tree.

• All applicable CI checks pass.

Risk and rollback

• Residual risks: Dockerfile worker build and PostgreSQL E2E require container execution; workspace dependency audit retains pre-existing Graph CLI/Wrangler advisories.
• Rollback or recovery plan: revert commit da65a162308c2652807672f32919c7fe431876fc or redeploy the prior API/worker image; durable UNKNOWN intents remain reconciliation-bound.

Human merge

• A human owner has reviewed the evidence and will perform the merge.
