refactor: remove buildSenseExamples, use @uncaged/nerve-skills for agent discovery

- Delete buildSenseExamples() (~25 lines of runtime file reading)
- Remove senseExamples from BuildSenseGeneratorDeps and BuildPlannerDeps
- Planner prompt now directs agent to read nerve-dev skill via npm package
- Clean up unused existsSync import

Closes xiaoju/nerve-workspace#2
