Fix: Correct version resolution for banner and update check (#511)

* Fix: Correct version resolution for banner and update check

Resolves issues where the tool's version was displayed as 'unknown'.

- Modified 'displayBanner' in 'ui.js' and 'checkForUpdate' in 'commands.js' to read package.json relative to their own script locations using import.meta.url.
- This ensures the correct local version is identified for both the main banner display and the update notification mechanism.
- Restored a missing closing brace in 'ui.js' to fix a SyntaxError.

* fix: refactor and cleanup

* fix: chores and cleanup and testing

* chore: cleanup
