MechaCat02 0973344515 feat(cli): collections manifest + ls + journeys; rename to kv::shared_collection (§11.6 C5)
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.

-- §11.6 (v1.2 Hierarchies): group-collection registry — shared cross-app data.
--
-- A row marks a collection NAME at a node as group-SHARED: every app in the
-- owning group's subtree may read it (and, with an authenticated editor+,
-- write it) via the explicit `kv::shared_collection("name")` SDK handle. Resolution is
-- nearest-ancestor-group-wins, walking the reading app's chain — that ancestry
-- walk is the isolation boundary (a foreign app's chain never contains the
-- owning group, so the name simply does not resolve). See docs §11.6.
--
-- This table holds only the MARKER (owner, name, kind) — the data itself lives
-- in a per-kind storage table (`group_kv_entries`, 0053, for kind='kv'). It is
-- pure declaration, structurally identical to an `extension_points` marker
-- (0051). A marker is config, not code → ON DELETE CASCADE.
--
-- Ownership is polymorphic (mirrors vars/secrets/scripts/extension_points):
-- exactly one of (app_id, group_id) is set. MVP authoring is restricted to
-- GROUP owners at the manifest layer (an app-declared shared collection is
-- degenerate — only that app would read it); the polymorphic shape keeps the
-- owner-generic reconcile path uniform with the other inheritable kinds.
--
-- `kind` is the storage discriminator. Only 'kv' ships in the MVP; the column
-- + CHECK exist now so docs/files/topics/queue slot in later without a
-- migration, and so a future `docs` collection of the same name is a distinct
-- row (the unique index covers `kind`).
