First commit of §7 multi-repo ownership. A 'project' is a repo-root that
declaratively manages a slice of the shared group tree; each group node is
owned by exactly one project (single-owner-per-node). This lands the registry
+ shared types and wires the inert 0047 `owner_project` seam — no behavior
change yet (claim logic is the next commit).
- migration 0066: `projects` table (UUID pk, unique slug, name, created_by →
admin_users ON DELETE SET NULL); `groups.owner_project` gains its FK →
projects(id) ON DELETE SET NULL (un-claim, never cascade-destroy a tree) +
an index.
- shared: `ProjectId` (id_type! macro) + `Project` struct; `Group` gains
`owner_project: Option<ProjectId>`.
- group_repo: GROUP_COLS + the ancestors recursive-CTE term now carry
`owner_project`, so `ancestors()` surfaces ownership for the nearest-claimed
fold; GroupRow + From updated.
- schema snapshot re-blessed; /version schema assertion 65 → 66.

Server-side foundation for Phase-2 groups (no group-owned resources yet):
Shared types:
- GroupId, Group; App gains group_id; AppRole::{precedence,max} for
folding the highest effective role across the membership chain.
Repos:
- group_repo: tree CRUD with reparent (ancestor-walk cycle guard under a
coarse instance-wide structural advisory lock; slug frozen; bumps
structure_version) and delete=RESTRICT (refuses non-empty groups).
- group_members_repo: per-(user, group) role grants, mirroring app_members.
Hierarchy-aware authz (§5.3):
- AuthzRepo gains effective_app_role / effective_group_role (default to
direct membership / none, so the ~18 existing test stubs are untouched);
the Postgres impl resolves each via one depth-bounded recursive CTE that
MAXes the app's own row with every ancestor group_members row.
- can(): the Member path now folds inherited group roles, so a group_admin
on any ancestor is implicitly app_admin beneath it. New Capability
variants InstanceCreateGroup / Group{Read,Write,Admin}; group caps carry
no app_id (bound API keys can't manage groups). 8 new unit tests.
Admin API:
- groups_api: group CRUD + reparent (admin at both source and destination
parent, §5.6) + per-group members, all capability-gated.
- apps: POST /apps takes an optional parent group (default root); app
responses carry group_id; my_role now reflects the effective role.
