Finish the §11.6 KV slice: declarative authoring, read-only inspection, the
runtime journey, and docs — plus a forced SDK-name fix.
- SDK name: `shared` is a Rhai RESERVED keyword, so `kv::shared(...)` is a parse
error. Renamed the handle constructor to `kv::shared_collection(...)`
(keeps the user's "shared" intent; unambiguous). Updated everywhere.
- CLI manifest: `collections = [...]` on `[group]` only (ManifestApp has no such
field + deny_unknown_fields → an app manifest carrying it is a hard error);
Manifest::collections() accessor; build_bundle emits it.
- plan/apply: a `collection` row group in `pic plan`; created/deleted counts in
the apply summary; collections threaded through PlanDto/NodePlanDto/
ApplyReportDto.
- read-only `pic collections ls --group` → GET /admin/groups/{id}/collections
(viewer+), backed by ApplyService::collection_report + CollectionInfo.
- journey: a group declares `catalog`; app A writes, app B (same subtree) reads
it back; a sibling-subtree app gets CollectionNotShared; `collections ls` +
re-apply NoOp. Full suite 114/114.
- docs: groups-and-project-tool §11.6 (KV-only MVP shipped + deferrals),
sdk-shape.md (the shared-collection handle + trust model), CLAUDE.md.

Data layer for shared cross-app group collections (KV-only MVP), nothing wired
yet. Two migrations + two repos, modeled on the extension_points (0051) marker
and the kv_entries (0007) store:
- 0052_group_collections.sql: owner-polymorphic marker table declaring a
collection name group-shared, with a `kind` discriminator (CHECK 'kv' for
now; generalizes to docs/files/topics/queue later) and per-owner
partial-unique (owner, LOWER(name), kind) indexes. CASCADE — a marker is
config, not code.
- 0053_group_kv_entries.sql: the shared store, keyed by (group_id, collection,
key) — NO app_id (a shared row belongs to the group). CASCADE on group delete
(data dies with its group, like vars/secrets config; an app delete leaves it).
- group_collection_repo: list_for_owner, insert/delete_collection_tx, and the
load-bearing resolve_owning_group — walks the reading app's chain
(CHAIN_LEVELS_CTE) for the nearest ancestor group declaring the name
(nearest-wins via ORDER BY depth LIMIT 1). That walk IS the isolation
boundary; the join is on group_owner only.
- group_kv_repo: a near-clone of kv_repo keyed by group_id.
Schema snapshot re-blessed (53 migrations).
