The core assist behavior has no verified functional defect, but non-English clients may see English-only tooltip guidance and the release contains an unclear note plus an accidental branch snapshot.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Add a localization key for the assist tooltip description.

RULEUCC_Guard selects Tooltips.assist. The tooltip renderer passes its description through LOC, but this value has no <LOC ...> key. Unlike the neighboring descriptions, localization packs cannot replace this text, so the guidance remains English for non-English clients. Add a unique localization key and use it here.

Correct the changelog wording.

The changelog targets players, but this entry has an unclear subject and inconsistent hyphenation. This can make the feature behavior harder to understand.

+- Add "Distribute Assisters": In a selection, take all mobile shields, scouts, and stealth gens, distribute assist orders to the remaining units, and change the selection to include only non-assisting units. Use the hotkey or right-click the assist icon. (`#7226`).

Remove the unreferenced q file.

q is a tracked snapshot of local Git branch output, including the current-branch marker. No repository source identifies it as an input, so it will become stale as branches change.
