Enhancement: Magnifying glass UX for resolved ambiguous comments

[nikomatsakis]

Enhancement Request

Improve the UX for resolved ambiguous comments by adding a magnifying glass icon that provides easy access to relocation functionality.

Current Behavior

• Ambiguous comments show generic text until resolved
• After resolution, sidebar shows the chosen location (e.g., "server/src/main.rs:15")
• To relocate, user must click the comment again and go through disambiguation

Proposed Enhancement

For resolved ambiguous comments, show:

• Chosen location text (current behavior)
• Magnifying glass icon 🔍 next to the text

Click behavior:

• Click text → Navigate to the comment location (current behavior)
• Click magnifying glass → Show relocation dialog directly

Benefits

• Clear visual indication that relocation is available
• Faster access to relocation without full re-disambiguation
• Better separation of navigation vs relocation actions

Implementation Notes

• Requires updating sidebar HTML generation
• Need separate click handlers for text vs icon
• Should preserve current navigation behavior for text clicks

Priority

Nice-to-have enhancement. Core functionality works well without this.
