Problem: Test suite was directly modifying user's personal ~/.ccs/
directory, causing configuration interference during development.
Solution:
- Add test-environment.js fixture with CCS_HOME env var support
- Update postinstall.js to respect CCS_HOME for test isolation
- Update config-manager.ts with getCcsHome() helper
- Update postinstall.test.js and cli.test.js to use isolated env
- Remove auto-install of .claude/ symlinks from postinstall
(users can run "ccs sync" to opt-in)
Benefits:
- Tests run in temp directories, no user config affected
- Users control when .claude/ items are installed via "ccs sync"
- All 39 tests passing with proper isolation
- Add comprehensive npm test scripts using mocha framework
- Add test:npm, test:native, test:unit, test:integration scripts
- Update main test script to run all test suites
- Fix npm test issues - all 34 tests now passing
- Use npx to run mocha without global installation
