refactor: remove dead code and unused files

- Remove duplicate web implementation (src/web.ts - 1,129 lines)
- Remove unused DailyNotification wrapper class (src/daily-notification.ts - 288 lines)
- Remove unused callback registry (src/callback-registry.ts - 413 lines)
- Remove unused example files (5 files, ~1,500 lines)
- Remove unused TypeScript modules (moved to test-apps/shared/typescript/)
- Remove unused interfaces (ContentHandler, ScheduleOptions)
- Remove outdated documentation files (VERIFICATION_*, GLOSSARY, etc.)
- Update import paths in test apps to use moved TypeScript modules
- Clean up README and USAGE.md references to deleted files

Total cleanup: ~3,330+ lines of dead code removed
Files deleted: 20 files
Files modified: 6 files (import path updates and documentation cleanup)

This significantly reduces codebase complexity and maintenance burden.
