chore(sync): linear sync remaining main fixes into develop

[T72]

Perform a linear main-to-develop synchronization for remaining main-only non-merge commits after release/governance updates.\n\nScope:\n- cherry-pick selected main commits onto a develop-based sync branch\n- preserve no-merge-commit policy\n- open PR with traceable commit list and validation evidence\n\nTarget commits:\n- a0e0775\n- 565a797\n- fde50a9\n- b4ef010\n- 108de36

[T72]

Outcome: attempted linear sync on branch chore/linear-sync-main-to-develop-20260302-b for commits a0e0775, 565a797, fde50a9, b4ef010, 108de36. All cherry-picks resolved as empty/no-op on current develop state (no net file changes), so no sync PR was created. This indicates those changes are already present or superseded on develop via other commits. Keeping issue closed as no-action required.
