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

Cleanup of already-fixed issue from commit 196b289.

**Background:**
- Bug was already fixed on Nov 2, 2025 (commit 196b289)
- 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.

Serves Method 1: "Make Using Emacs Frictionless"
- Quick win: ~2 minutes (just cleanup)
- Reduces code clutter

+CLOSED: [2025-11-03 Sun]
 
 Error: "Debugger entered--Lisp error: (void-variable go-ts-mode-map)"
 Location: modules/prog-go.el - trying to bind keys before mode loads.
-Fix: Wrap keybinding in with-eval-after-load or check if variable is bound.
+
+✅ Already fixed in commit 196b289 (Nov 2, 2025)
+- Moved keybinding from `:bind (:map go-ts-mode-map ...)` to hook function
+- Keybinding now set in `cj/go-mode-keybindings` called via `:hook`
+- Function executes after mode loads, ensuring keymap exists
+- Today's cleanup: Removed unused forward declarations (lines 34-35)
+
+Fix was: Wrap keybinding in hook function instead of :bind clause.
+Result: No more void-variable error, keybinding works correctly.
