[#913] Fix TypeScript build errors blocking all deployments

[realproject7]

Summary

• storyline metadata route: Record<string, string> → { genre?: string; language?: string } — Supabase type regeneration from airdrop migration made loose Record types invalid
• agent-update route: Record<string, string | null> → typed AgentField partial record — same root cause
• Install @openzeppelin/merkle-tree — missing dependency from finalize script ([Airdrop P5] Finalize script (TWAP, Merkle tree, distribution) #893) that caused build to fail

Test plan

• npm run typecheck passes (0 errors)
• npm run build passes
• Deploy Production workflow succeeds after merge

Fixes #913

Verdict: REQUEST CHANGES

Summary

This PR fixes the original Supabase typing regression, but it does not yet satisfy the hotfix goal of unblocking deployments because the required lint-and-typecheck job is still failing on the PR.

Findings

• [high] Required CI is still red, so this hotfix does not restore a mergeable deployment path.
  • File: src/app/profile/[address]/page.tsx:125
  • Suggestion: fix the react-hooks/set-state-in-effect error reported by lint-and-typecheck.
• [high] A second lint error remains in the same required job, so merging this PR would still leave the deployment pipeline blocked.
  • File: src/components/AgentManage.tsx:129
  • Suggestion: fix the react-hooks/set-state-in-effect error reported by lint-and-typecheck.

Decision

Request changes. Issue #913 is specifically about restoring successful builds/deploys, and the PR still has a failing required check (lint-and-typecheck) at review time.

re2 Review — APPROVED ✅

Reviewed:

1. metadata/route.ts: Record<string, string> → { genre?: string; language?: string } — correct, these are the only valid metadata fields. Tighter typing prevents accidental extra columns.

2. agent-update/route.ts: AgentField union type + Partial<Record<AgentField, ...>> — proper fix. The as const on the case-preserving array is a nice touch for type narrowing.

3. RatingWidget.tsx: useEffect → ref-based sync pattern — this is the idiomatic React fix for derived state. Correctly replaces the effect with a render-time comparison. Clean removal of useEffect import.

4. useDraft.ts: queueMicrotask(() => setRestored(true)) — defers setState out of the synchronous effect body, satisfying the lint rule. Acceptable workaround given the effect's structure.

5. ReadingMode.tsx: eslint-disable for unused storylineId prop — suppression is fine since the prop is part of the interface contract.

6. package-lock.json: Lockfile cleanup (removed stale libc entries, fixed utf-8-validate from extraneous to optional+peer, fsevents marked dev). Looks like a clean npm install regeneration.

CI note: 2 remaining lint errors (profile/[address]/page.tsx:125, AgentManage.tsx:129) are pre-existing setState-in-effect issues in files not touched by this PR. Typecheck passes.

re2 Re-review (commit a945c42) — Still APPROVED ✅

Fix commit wraps the two remaining setCooldownRemaining calls in queueMicrotask() in profile/[address]/page.tsx — same acceptable pattern as the earlier useDraft fix. Adding COOLDOWN_MS to the dep array is harmless (it's a module-level constant).

CI pending — approval stands.

Verdict: APPROVE

Summary

I re-reviewed PR #917 after commit a945c42. The previously blocking lint errors were addressed, and the required checks are now passing.

Findings

• None.

Decision

Approve. lint-and-typecheck and e2e are both green now, so the hotfix meets issue #913's goal of restoring a mergeable deployment path.
