Claude 441413ea95 feat(concord): roles & moderation write path (CORD-04)
ConcordModeration builds the Control Plane editions for defining a role,
granting roles to a member, and banning/unbanning — each a kind-3308 edition,
plaintext-sealed and wrapped on the Control Plane. It chains the next version
onto the entity's current head (version+1, prevHash=head.hash) and unions the
banlist, taking the community's current editions as input.

Authority is enforced at fold time by the AuthorityResolver, not here: a round-
trip test confirms an owner can define an Admin role, grant it (member gains BAN),
ban/unban (version chaining heals), and that a grant forged by a non-outranking
troll is dropped by the fold.

- ConcordActions.controlEditions opens control wraps into editions
- ConcordCommunitySession exposes controlEditions()/controlPlaneKey() so edits
  chain onto live state
- Account.grantConcordRole / banConcordMember / unbanConcordMember publish the
  edition with an instant local echo (the session refolds it)
