* Add implementation plan for commissioner-without-team feature
https://claude.ai/code/session_01NSRMSYtb7jSFbngDS8okn3
* Allow commissioners to exist without owning a team
- Add opt-out checkbox on league creation ("I want to play in this league")
so the creator can be commissioner-only without claiming a team
- Add Commissioner Management card to league settings with add/remove
commissioner UI; guards against removing the last commissioner
- Add countCommissionersByLeagueId model helper for the last-commissioner guard
- Show "No team" indicator on the league homepage next to commissioners
who don't own a team in the current season

* Fix code review issues in commissioner management
- Add success/error feedback banners to commissioner add/remove actions
- Gate allUsers query to admin-only (prevents exposing all users to non-admin commissioners)
- Prevent commissioner self-removal in both action (server) and UI (client)
- Add "(you)" label next to current user in commissioner list
- Remove all unnecessary `any` type casts in favor of inferred types

* Allow commissioners to add league members as co-commissioners
Non-admin commissioners can now add users who already own a team in
the league as co-commissioners. Admins still see the full user list.
Previously the add-commissioner form was admin-only.
