Changes

• The requester always gives a route's Pregame direction sequence 0 and Postgame sequence 1. Other routes keep the upstream order. Right now 6 of the 12 Gameday routes list Postgame first.
• New route.isLoop column. It is false when longName starts with "Gameday". The migration starts existing rows at true, and the next route data sync marks the Gameday routes.
• New sync stream RoutesV2 → RouteV2 (adds isLoop) + RouteDeleteV2. RoutesV1 is unchanged.
• openapi.json is regenerated.

Notes

• isLoop has no bun default tag. With one, bun inserts DEFAULT for a false value, and Gameday routes would be stored as true. A medium test in route_data_repository_test.go covers this.
• RoutesV2 has its own delete type because the SyncStreams unit test requires it. I added a row to docs/design/sync-stream.md.

Old app compatibility

• RoutesV1 lines still leave out isLoop. A controller test covers this.
• Requesting RoutesV1 and RoutesV2 together returns 400.
• When a client moves from V1 to V2, it gets every route again in the V2 shape.
• Old apps also get the Pregame/Postgame order, because a changed sequence re-sends those DirectionV1 rows.

Deploy

Deploy this before the matching app release. The app requests RoutesV2.
