Colorize all visible editors instead of active one

[sr-tream]

This PR addresses two issues:

1. Only the active editor was colorized when opening a workspace with multiple editors.
2. Editors could lose colorization during certain operations.

Changes:

• Modified extension to colorize all visible editors, both on workspace open and during editor changes.
• Implemented a custom, editor-aware debounce function to replace 'just-debounce'.

Note: Removed 'just-debounce' from dependencies, updating package.json.
