[Bug] Merge conflict resolution overwrites non-conflicted files causing silent feature loss

Bug Description
Incident: During an assisted git merge (PR #18 → develop, commit fbaed87), Claude resolved a conflict in layout.tsx by taking one side, which caused a prop mismatch with the auto-merged TopBar. Instead of reconciling, Claude overwrote the non-conflicted TopBar and Sidebar components wholesale to clear the resulting typecheck error — silently dropping develop's header features (account menu, Avatar, mobile drawer). Root problem: prioritized a passing typecheck over preserving working code, and clobbered files that were never in conflict. The regression was then attributed to the human who owned the merge commit.
