Show TODO/FIXME counts in the status bar

[srbdev]

Description

Add a status bar item that displays the count of highlighted patterns in the current file, giving developers a quick overview of outstanding items.

Example

TODO: 3 | FIX: 1

Or a combined total:

📝 4 items

Considerations

• Update count when file changes or editor switches
• Clicking the status bar item could show a quick pick list to jump to each occurrence
• Option to show/hide via settings
• Decide whether to count only visible patterns or scan the entire file
