test: add unit tests and work packet for NIP-88 polls

Add 15 unit tests covering: - Poll creation authorization (app dev, zapstore team, random user) - Npub to hex conversion for author filtering - Response deduplication (one vote per pubkey, latest wins) - Vote counting for single/multi-choice polls - Poll expiration logic Add work packet (WORK-002) per PR #271 spec-first workflow.

+# WORK-002 — NIP-88 Polls
+
+**Feature:** FEAT-002-nip88-polls.md
+**Status:** Complete
+
+## Tasks
+
+- [x] 1. Create Poll and PollResponse models in models package
+  - Files: `models/lib/src/models/poll.dart`, `models/lib/src/models/poll_response.dart`
+  - Notes: Kind 1068 for polls, kind 1018 for responses per NIP-88
+- [x] 2. Register models in storage
+  - Files: `models/lib/src/storage/storage.dart`
+- [x] 3. Create PollsSection widget
+  - Files: `lib/widgets/polls_section.dart`
+  - Notes: Follows CommentsSection pattern
+- [x] 4. Integrate into AppDetailScreen
+  - Files: `lib/screens/app_detail_screen.dart`
+- [x] 5. Add author filtering (app dev + zapstore team)
+  - Files: `lib/widgets/polls_section.dart`
+  - Notes: Convert npubs to hex for query filter
+- [x] 6. Add poll creation for authorized users
+  - Files: `lib/widgets/polls_section.dart`
+  - Notes: Modal with question, options, poll type, expiration
+- [x] 7. Fix hooks order mismatch in poll creation
+  - Notes: Replace useListenable loop with useEffect listener pattern
+- [x] 8. Fix duplicate author field in Poll model
+  - Files: `models/lib/src/models/poll.dart`
+  - Notes: Author field inherited from Model base class
+- [x] 9. Self-review against INVARIANTS.md
+- [x] 10. Add automated tests
+  - Files: `test/widgets/polls_section_test.dart`
+  - Notes: 15 unit tests for authorization, deduplication, vote counting, expiration
+
+## Test Coverage
+
+| Scenario | Expected | Status |
+|----------|----------|--------|
+| Display polls for app | Polls from authorized authors shown | [x] Manual |
+| Vote on single-choice poll | Selection replaces previous, vote submitted | [x] Manual |
+| Vote on multi-choice poll | Can toggle multiple selections | [x] Manual |
+| Expired poll | Shows "Ended" badge, voting disabled | [x] Manual + Unit |
+| User already voted | Their selection highlighted | [x] Manual |
+| Create poll as app dev | Modal opens, poll created and displayed | [x] Manual + Unit |
+| Create poll as non-dev | Create button not shown | [x] Manual + Unit |
+| Duplicate votes per pubkey | Only latest vote counted | [x] Manual + Unit |
+| Poll with no votes | Shows "0 votes" | [x] Manual + Unit |
+| Network failure on vote | Error shown, selection preserved | [ ] |
+| Unsigned user tries to vote | Sign-in prompt shown | [x] Manual + Unit |
+| Npub to hex conversion | Zapstore team npubs convert correctly | [x] Unit |
+
+## Decisions
+
+### 2026-01-26 — Poll author filtering
+
+**Context:** Anyone could spam polls on app pages.
+**Options:** No filtering, WoT filtering, explicit allowlist.
+**Decision:** Explicit allowlist (app developer + zapstore team npubs).
+**Rationale:** Simple, effective spam prevention. WoT can be added later.
+
+### 2026-01-26 — Poll creation scope
+
+**Context:** Initially planned as view/vote only.
+**Options:** No creation, creation for anyone, creation for authorized users.
+**Decision:** Creation for app developers on their apps + zapstore team on any app.
+**Rationale:** Developers should be able to gather feedback on their own apps.
+
+### 2026-01-26 — Models package location
+
+**Context:** Poll/PollResponse models needed, models is external package.
+**Options:** Add to zapstore directly, fork models, contribute to models.
+**Decision:** Create feature branch in cloned models repo.
+**Rationale:** Models belong in models package per architecture guidelines.
+
+## Spec Issues
+
+_None_
+
+## Progress Notes
+
+**2026-01-26:** Initial implementation complete with poll display, voting, and creation.
+**2026-01-26:** Fixed hooks mismatch and author field double-initialization bugs.
+**2026-01-26:** Fixed npub to hex conversion for query filter.
