Claude c236474f88 feat(nip29): timeline refs, custom roles, subgroup nav, naddr invites
Follows up the subgroup protocol work with four NIP-29 compliance/UX gaps.

previous timeline references (spec §Timeline references):
- RelayGroupChannel.previousEventRefs(): first-8-char id prefixes of the most
  recent events seen from the host relay, excluding the sender's own, capped at
  the spec's 50-event window. Only draws from events actually received in the
  channel so the host relay is known to have them.
- Populate the `previous` tag on all outgoing group events: kind-9 chat and
  replies, kind-1111 minichat comments, kind-11 threads, and group replies.

Custom roles (kind 39003):
- Route SupportedRolesEvent onto the channel (LocalCache.consume + a
  RelayGroupChannel.supportedRoles field) instead of only storing it.
- Members screen: when the relay advertises a role set, offer those roles when
  assigning (admins), and show each member's real relay-assigned role label
  instead of collapsing everything to admin/moderator. Falls back to the
  built-in admin/moderator shortcuts when no 39003 is published.

Subgroup navigation (spec §Subgroups):
- RelayGroupSubgroupsBar: a self-hiding bar under the pinned bar showing a
  breadcrumb up to the parent group and chips for the child subgroups (in the
  relay's `child` order), each opening that group on the same host relay.

naddr invite codes (spec §Group identifier):
- GroupNAddrInvite parses the `naddr1…?invite=<code>` suffix; both the tap
  handler (ClickableRoute) and the deep-link handler (MainActivity) now feed it
  into the kind-9021 join request so a shared invite naddr auto-joins.

Tests for the naddr invite parser. spotless clean; quartz tests green;
amethyst compiles.
