Apr 17, 2026

Display current JSON path and value in status line (#62, #63)
Add shortcut (Ctrl-C) to copy current path and value (#64)
Value search feature (#65)
- / : search forward
- ? : search backward
- n : repeat search in the same direction
- N : repeat search in the opposite direction
- Search applies to values only (keys are ignored)

  - true, false, nil → literals
  - others → treated as a string
