Chris Farhood 286e88fece feat: implement Result types for type-safe error handling (Phase 1.1) 
Replace throw/catch patterns with explicit Result types throughout the
codebase. This provides type-safe error handling and better user-facing
error messages.

## Changes

### Core Type System (src/types.ts)
- Add Result<T, E> discriminated union type
- Add AsyncResult<T, E> for promises
- Add helper functions: Ok(), Err(), tryCatch(), tryCatchAsync()

### Crypto Module (src/lib/crypto.ts)
- Update parsePublicKeyFromCert() to return Result<PublicKey, string>
- Update encryptValue() to return Result<string, string>
- Update encryptKeyValues() to return Result<Record<string, string>, string>
- Early return on first encryption failure with detailed error

### Controller API (src/lib/controller.ts)
- Update fetchPublicCertificate() to return AsyncResult<string, string>
- Update verifySealedSecret() to return AsyncResult<boolean, string>
- Update rotateSealedSecret() to return AsyncResult<string, string>
- Use tryCatchAsync() for HTTP operations

### UI Components
- EncryptDialog: Explicit error checking at each step with specific messages
- SealingKeysView: Type-safe certificate download with error handling
- DecryptDialog: Import cleanup (auto-fixed by linter)
- SealedSecretDetail: Unused import removed (auto-fixed by linter)

### Documentation
- ENHANCEMENT_PLAN.md: Comprehensive 4-phase enhancement roadmap
- PHASE_1.1_COMPLETE.md: Detailed implementation summary
- BUILD_VERIFICATION_SUMMARY.md: Build metrics and verification results
- DEVELOPMENT.md: Development workflow guide
- TESTING_GUIDE.md: Manual testing procedures
- READY_FOR_TESTING.md: Quick-start testing guide

### Development Tools
- Add 5 specialized Claude Code subagents to .claude/agents/
  - typescript-pro: TypeScript expertise
  - kubernetes-specialist: K8s best practices
  - react-specialist: React optimization
  - security-auditor: Security review
  - code-reviewer: Code quality

## Benefits

- Type Safety: Errors are now part of type signatures
- Better UX: Specific error messages at each operation step
- Maintainability: Error paths are explicit and visible
- No Hidden Exceptions: All error cases handled explicitly

## Verification

- TypeScript: 0 errors
- Linting: All checks pass
- Build: 340.13 kB (93.40 kB gzipped, +0.2%)
- Package: Successfully created

## Breaking Changes

None for users. Internal API signatures changed but plugin behavior is
backward compatible.

## Testing

See TESTING_GUIDE.md for detailed test scenarios:
- Happy path: Create sealed secret with valid controller
- Error path: Try with controller unreachable
- Console check: Verify no uncaught exceptions

Run: npm start (in headlamp-sealed-secrets directory)

🚀 Ready for Iterative Development

What's Working

✅ Build pipeline fully functional ✅ Code quality tools configured ✅ Package creation automated ✅ TypeScript strict mode passing ✅ No linting errors

Development Workflow Verified

# 1. Make changes
npm start  # Hot reload during development

# 2. Verify quality
npm run lint-fix
npm run tsc
npm run build

# 3. Package
npm run package

# 4. Test
headlamp plugin install ./headlamp-sealed-secrets-0.1.0.tar.gz

🎯 Next Steps

Immediate Actions

  1. Set Up Testing (Phase 4 prerequisite)

    npm install -D vitest @testing-library/react @testing-library/user-event

  2. Test Plugin Installation

    # Install to Headlamp
headlamp plugin install ./headlamp-sealed-secrets-0.1.0.tar.gz

# Or manually test
npm start
# → http://localhost:4466

  3. Verify Against Real Cluster

    # Ensure sealed-secrets controller is running
kubectl get deployment -n kube-system sealed-secrets-controller

# Test plugin features
npm start

Enhancement Implementation Strategy

Approach: Iterative, test-driven development

  1. Start Small - Begin with Phase 1 Task 1.1 (Result types)
  2. Build & Test - After each task: 
    npm run build
npm run package
# Test manually in Headlamp
  3. Commit Often - Small, focused commits per task
  4. Deploy to Test Cluster - Validate each enhancement

Recommended Implementation Order

Phase 1A - Quick Wins (Week 1)

  1. Result types (1.1) - 1-2 days
  2. Branded types (1.2) - 1 day
  3. Build, test, commit

Phase 2A - High-Value K8s Features (Week 2) 4. Certificate validation (2.1) - 2 days 5. Controller health check (2.2) - 1.5 days 6. Build, test, commit

Phase 3A - Critical UX (Week 3) 7. Custom hooks (3.1) - 2 days 8. Form validation (3.2) - 1.5 days 9. Build, test, commit

Continue with remaining phases...
