feat: enhance Claude Code setup with slash commands, hooks, and verification

Add slash commands for common workflows:
- /commit-push-pr: Streamlined PR creation
- /verify: Full verification suite (lint + test + build)
- /test: Run tests with results summary
- /lint-fix: Auto-fix lint and formatting
- /review: Code review for quality and Nostr patterns

Update settings.json:
- Expand permissions for common safe bash commands
- Add PostToolUse hook for auto-formatting with Prettier

Update CLAUDE.md:
- Add Verification Requirements section
- Document available slash commands
- Emphasize running /verify before PRs

+Diff stats: ${{ git diff --stat HEAD~1 2>/dev/null || git diff --stat }}
+Recent commits: ${{ git log --oneline -5 }}

+Instructions:
+1. Review the changes and stage relevant files
+2. Create a commit with a clear, descriptive message following repo conventions
+3. Push to the current branch (or create a new branch if on main)
+4. Create a PR with:
+   - Clear title summarizing the change
+   - Summary section with bullet points
+   - Test plan section describing how to verify
+
+Do NOT push to main/master directly.

+Analyze the changes for:
+
+## 1. Nostr Protocol Compliance
+- Correct event kinds used for the feature
+- Proper tag structures (NIP-10 threading, NIP-19 identifiers, etc.)
+- Appropriate handling of replaceable vs regular events
+
+## 2. Applesauce Patterns
+- Using EventStore singleton (not creating new instances)
+- NOT wrapping applesauce helpers in useMemo (they cache internally)
+- Proper subscription cleanup in useEffect
+- Using reactive patterns (observables) correctly
+
+## 3. React Best Practices
+- No missing dependencies in useEffect/useMemo/useCallback
+- Proper cleanup functions in useEffect
+- No unnecessary re-renders or state updates
+
+## 4. Code Quality
+- Follows existing patterns in the codebase
+- No over-engineering or unnecessary abstractions
+- Security considerations (XSS prevention, input validation)
+- Proper error handling where needed
+
+## 5. Architecture Alignment
+- Uses path alias (@/) correctly
+- Follows file organization conventions
+- State mutations go through logic.ts pure functions
+
+Provide specific, actionable feedback with `file:line` references.

+## Verification Requirements
+
+**CRITICAL**: Before marking any task complete, verify changes work correctly:
+
+1. **For any code change**: Run `npm run test:run` - tests must pass
+2. **For UI changes**: Run `npm run build` - build must succeed
+3. **For style/lint changes**: Run `npm run lint` - no new errors
+
+**Quick verification command**:
+```bash
+npm run lint && npm run test:run && npm run build
+```
+
+If tests fail, fix the issues before proceeding. Never leave broken tests or a failing build.
+
+### Slash Commands
+
+Use these commands for common workflows:
+- `/verify` - Run full verification suite (lint + test + build)
+- `/test` - Run tests and report results
+- `/lint-fix` - Auto-fix lint and formatting issues
+- `/commit-push-pr` - Create a commit and PR with proper formatting
+- `/review` - Review changes for quality and Nostr best practices
