feat: add TypeScript support and shared types

- Added TypeScript configuration file (tsconfig.json) with strict settings.
- Introduced devDependencies for TypeScript in package.json.
- Added scripts for type checking and watching for changes.
- Created a new types file (lib/types.ts) defining shared types for the DevClaw plugin.

lib/tools/task-pickup.ts
