Stop syncing legacy model JSON files in sync-actions

[Copilot]

sync-actions.yml still treated .github/aw/models.json and .github/aw/model-multipliers.json as sync inputs, even though this repository only carries the compatibility matrix files. That produced avoidable warnings when syncing older gh-aw refs where those files do not exist.

• Scope the sync to actual repo-owned files

  • Remove models.json and model-multipliers.json from the .github/aw cleanup and copy loop.
  • Keep sync behavior limited to:
    • .github/aw/compat.json
    • .github/aw/compat.schema.json

• Align logging with synced artifacts

  • Update the post-sync listing to report only compat* files, so logs reflect the actual sync contract.

• Align staging with synced artifacts

  • Remove the legacy model files from the guarded git add -A loop used before PR creation.

for f in compat.json compat.schema.json; do
  src="gh-aw/.github/aw/$f"
  dst="gh-aw-actions/.github/aw/$f"
  if [ -f "$src" ]; then
    cp "$src" "$dst"
  fi
done

Updated in 387cf15 — I clarified in sync-actions.yml that model data files are synced from actions/setup/js during the action-folder rsync step, not from .github/aw.
