Backlinks panel: show notes linking to current note

[ryuhmanov-m]

Parent issue: #31

Context

Wikilinks ([[Note]]) create connections between notes, but there's no way to see which notes link to the current note (backlinks). This is a core knowledge management feature.

Scope

1. Backend: Query the chunks table for chunks containing [[Current Note Name]] pattern
   • Or parse wikilinks during indexing and store in a links table
2. Frontend: Show a "Backlinks" section at the bottom of the note view (or as a panel)
   • List note titles that contain links to the current note
   • Show a small context snippet around each link
   • Click to navigate to the linking note

Approach options

Simple (recommended for GFI): Use kb_search or a direct SQL query for [[note name]] across chunks. No new tables needed.

Advanced (follow-up): Parse wikilinks during indexing, store in a dedicated links table with source_file, target_file, context. More performant for large vaults.
