Fix merge conflicts

Trigger

Branch has unresolved merge conflicts and needs a reliable path to a buildable state.

Workflow

1. Detect all conflicting files from git status and conflict markers.
2. Resolve each conflict with minimal, correctness-first edits.
3. Prefer preserving both sides when safe. Otherwise, choose the variant that compiles and keeps public behavior stable.
4. Regenerate lockfiles with package manager tools instead of hand-editing.
5. Run compile, lint, and relevant tests.
6. Stage resolved files and summarize key decisions.
