Migrate this group's metadata from the legacy GroupContextExtensions shape onto OpenMLS AppDataUpdate proposals. After this returns successfully, subsequent metadata writes (group name, description, image URL, admin list, permissions) flow through the proposal-based path instead of GCE commits.
Parameters
Skip the key-package capability check. Before you set this to true, verify that every member supports proposals and has a version at or above minVersion. Defaults to false.
Override the MIN_SUPPORTED_PROTOCOL_VERSION floor. null defaults to libxmtp's PROPOSALS_MIN_PROTOCOL_VERSION — the release where proposals support first ships.
Hard-fails if force == false and any member's latest key package doesn't advertise ProposalType.AppDataUpdate. The migration is one-way — a migrated group cannot return to the legacy path.
