fix(repo): Version unification and repo hygiene improvements

Version Unification:
- Updated README.md version from 2.2.0 → 1.0.11
- Updated src/definitions.ts version from 2.0.0 → 1.0.11
- Documented package.json as source of truth

Repo Hygiene:
- Added *.tar.gz and docs.tar.gz to .gitignore
- Added build/reports/ and .gradle/nb-cache/ to .gitignore
- Strengthened Android .gradle exclusions

Created docs/FEEDBACK-RESPONSE-PLAN.md with action plan for
addressing ChatGPT feedback.

Verification:
- Version headers now match package.json ✅
- .gitignore strengthened ✅

+# ChatGPT Feedback Response Plan
+
+**Purpose:** Action plan to address feedback from ChatGPT code review  
+**Owner:** Development Team  
+**Last Updated:** 2025-12-23  
+**Status:** active
+
+---
+
+## Priority 1: Quick Wins (High ROI, Low Risk)
+
+### 1.1 Repo Hygiene ✅ IN PROGRESS
+- [x] Check what build artifacts are tracked in git
+- [ ] Remove tracked build artifacts from git
+- [ ] Strengthen `.gitignore` (add `*.tar.gz`, `build/reports/`, etc.)
+- [ ] Verify `package.json` `files` field excludes build artifacts
+- [ ] Clean up any nested archives
+
+### 1.2 Version Unification ✅ IN PROGRESS
+- [ ] Update `README.md` version from 2.2.0 → 1.0.11
+- [ ] Update `src/definitions.ts` version from 2.0.0 → 1.0.11
+- [ ] Add CI check script to verify version consistency
+- [ ] Document version policy: `package.json` is source of truth
+
+---
+
+## Priority 2: Structural Improvements (Medium ROI, Medium Risk)
+
+### 2.1 Native Plugin Refactoring
+- [ ] Analyze `DailyNotificationPlugin.kt` (~2,782 lines) - extract services
+- [ ] Analyze `DailyNotificationPlugin.swift` (~2,047 lines) - extract services
+- [ ] Create service extraction plan:
+  - `SchedulerService`
+  - `PermissionService`
+  - `Power/ExactAlarmService`
+  - `ReactivationService`
+  - `RollingWindowService`
+  - `Storage/StateRepository`
+  - `FetcherBridge`
+- [ ] Implement refactoring in small, mergeable batches
+
+### 2.2 TODO Classification
+- [ ] Audit all TODOs/FIXMEs/HACKs (found 34 instances)
+- [ ] Classify into:
+  - **Must ship** (correctness, rate-limits, TTL, scheduling)
+  - **Nice-to-have** (perf metrics, stats, diagnostics)
+  - **Future** (Phase 2)
+- [ ] Create issues for "must ship" items
+- [ ] Move "Phase 2" items behind feature flags or to planning docs
+
+---
+
+## Priority 3: CI/CD Infrastructure (High ROI, Low Risk)
+
+### 3.1 CI Workflows
+- [ ] Create `.github/workflows/ci.yml`:
+  - Node/TS: lint, typecheck, unit tests, build, `npm pack` check
+  - Android: `./gradlew test` + `lint` + `assembleDebug`
+  - iOS: `xcodebuild test` (macOS runner)
+- [ ] Add merge gates on CI passing
+- [ ] Document CI setup in `ci/README.md`
+
+### 3.2 Test Coverage
+- [ ] Identify critical paths needing tests:
+  - Backoff policy correctness
+  - Idempotency key behavior
+  - Watermark monotonicity
+  - TTL-at-fire logic
+  - Rolling window / rate-limit counters
+  - Permission flows (Android 13+, exact alarm, battery optimization)
+
+---
+
+## Priority 4: Packaging & Workspace (Medium ROI, Low Risk)
+
+### 4.1 Workspace Package Dist
+- [ ] Check if `packages/polling-contracts/dist/` is committed
+- [ ] If committed, remove from git
+- [ ] Add `prepack` script to build subpackage before publish
+- [ ] Update `package.json` `files` to control publishing
+
+---
+
+## Priority 5: Documentation (Low ROI, Low Risk)
+
+### 5.1 Documentation Consolidation
+- [ ] Update `README.md` with clear entry points:
+  - Install
+  - Minimal usage example
+  - Platform setup (Android/iOS)
+  - Troubleshooting link
+  - Architecture link
+- [ ] Add Compatibility Matrix:
+  - Capacitor versions supported
+  - Android minSdk/targetSdk
+  - iOS min version
+  - Exact alarm behavior notes per Android version
+- [ ] Add Behavioral Contracts section:
+  - Guaranteed behaviors (monotonic watermark, idempotency, TTL)
+  - Best-effort behaviors (delivery in Doze, background fetch timing)
+

+
+## Execution Order
+
+1. **Week 1**: Quick wins (Repo hygiene, Version unification)
+2. **Week 2**: CI/CD infrastructure
+3. **Week 3-4**: Native plugin refactoring (in batches)
+4. **Week 5**: TODO classification and cleanup
+5. **Week 6**: Documentation improvements
