test: migrate test suite to gem structure

- Copy test files from source (~/github/second-brain/tests/reclaim/)
- Create test/test_helper.rb with proper gem loading
- Update test/test_reclaim.rb to use gem structure (remove old require paths)
- Fix CLI unused variable warnings (NotFoundError rescues)
- Update CLI test to match new command name ('reclaim' vs 'ruby script.rb')

Test results:
- 45 runs, 148 assertions, 0 failures, 0 errors
- 7 skips (integration tests require RECLAIM_TOKEN)
- All unit tests passing: Task, Client, Utils, CLI
- Test coverage maintained from original implementation
