fix: resolve scheduler errors and reorganize type definitions

## Scheduler Fixes
- Fixed "TypeError: this.processDueTasks is not a function" in task runner
- Resolved ArangoDB task execution context issues by implementing inline processing
- Enhanced task registration cleanup to prevent duplicate scheduler tasks
- Improved error handling with proper logging and graceful degradation
- Simplified watchdog implementation to avoid re-registration loops

## Type System Improvements
- Moved types/ folder from root to src/types/ for better project organization
- Updated jsconfig.json files to include TypeScript declaration files
- Added @types/* path mapping for cleaner type imports
- Enhanced IDE support with proper type resolution configuration
- Updated type documentation with corrected import paths

## Technical Details
- Scheduler now uses inline task processing to avoid context binding issues
- Comprehensive cleanup of orphaned task registrations on service restart
- Improved type discovery for better IntelliSense and autocomplete support
- Maintained backward compatibility while fixing underlying implementation bugs
