fix: resolve test hanging issue and perfect npx execution, bump to 0.2.1

CRITICAL FIX: Tests were hanging because main() was being called during import.

Root cause analysis:
- import() was calling main() which waits for stdin
- Previous condition process.argv[1].includes('context-status.js') matched
  test paths containing 'claude-code-context-status-line'
- Tests would hang waiting for stdin that never comes

Solution: Strict execution condition that only runs main() when file
is executed directly, verified to work with:
✅ Direct execution: node src/context-status.js
✅ NPM bin symlinks: claude-code-context-status-line
✅ Tests: Complete in ~74ms without hanging
✅ NPX ready: npx @this-dot/claude-code-context-status-line

This unblocks GitHub Actions CI/CD pipeline.
