chore: Remove unused go-ts-mode-map forward declarations

Cleanup of already-fixed issue from commit e286f96.

**Background:**
- Bug was already fixed on Nov 2, 2025 (commit e286f96)
- Original error: "void-variable go-ts-mode-map"
- Fix moved keybindings from :bind clause to hook function
- Keybindings now set after mode loads via cj/go-mode-keybindings

**This Cleanup:**
- Removed unused forward declarations (lines 34-35):
  - (defvar go-ts-mode-map)
  - (defvar go-mod-ts-mode-map)
- These were artifacts from the original buggy implementation
- No longer needed since keybindings use local-set-key in hook

**Testing:**
- ✓ File compiles cleanly without warnings
- ✓ No references to these variables exist in codebase
- ✓ Keybindings work correctly via hook function

Updated todo.org to mark task as complete, documenting that it was
already fixed and today's work was just cleanup.
