fix: resolve TypeScript typecheck errors in Phase 0 implementation

- Fix git-utils import in PreflightChecker using require() with type casting
- Fix ConfigManager initialization in TaskLoaderService (use async factory)
- Fix TaskService.getTask return type (returns Task | null directly)
- Export PreflightChecker and TaskLoaderService from @tm/core
- Fix unused parameter and type annotations in autopilot command
- Add boolean fallback for optional dryRun parameter

All turbo:typecheck errors resolved.
