fix(plugin): resolve build issues and improve project structure

- Fix TypeScript compilation errors and interface mismatches
- Update interface definitions with complete type safety
- Resolve build system issues with Rollup configuration
- Fix web implementation and method signatures
- Update test files to match current interfaces
- Remove duplicate Jest configuration
- Add comprehensive project assessment documentation

Core Improvements:
- Complete interface definitions with proper type safety
- Fix validation logic in daily-notification.ts
- Update web platform implementation with all required methods
- Resolve module import/export issues
- Convert Rollup config to CommonJS for compatibility

Documentation:
- Add PROJECT_ASSESSMENT.md with comprehensive analysis
- Create CRITICAL_IMPROVEMENTS.md with detailed roadmap
- Add IMPROVEMENT_SUMMARY.md with current status
- Document missing Android implementation requirements
- Outline priority improvements and timeline

Build System:
- Fix Rollup configuration syntax
- Remove duplicate Jest configuration
- Ensure successful TypeScript compilation
- Resolve all module resolution issues

Testing:
- Update test files to match current interfaces
- Fix mock implementations and expectations
- Align test structure with actual implementation

Breaking Changes:
- Updated interface definitions for better type safety
- Removed non-existent method references
- Fixed timestamp types (string vs number)

Dependencies:
- No new dependencies added
- Build system compatibility improved
- TypeScript configuration optimized

The project now builds successfully and has a clear roadmap for
restoring the missing Android implementation and completing
production-ready features.
