fix: resolve script execution issue for npx and global install, bump to 0.1.8

The root issue was the import.meta.url execution check not working with npm bin symlinks.

Changes:
- Replace complex execution detection with simple main() call
- This ensures the script runs in all contexts: direct execution, npm bin, npx
- Short bin name 'ccstatus' works with npx -p syntax
- Both global install and npx now produce correct output

✅ Working: echo '...' | ccstatus
✅ Working: echo '...' | npx ./package.tgz
✅ Ready for: echo '...' | npx -p @this-dot/claude-code-context-status-line ccstatus
