Global env-var ceilings enforced in the group write path (mirrors the
per-value caps): PICLOUD_GROUP_KV_MAX_ROWS / _DOCS_MAX_ROWS (per-group row
count, checked only on a NEW key/doc — updates exempt) and
_FILES_MAX_TOTAL_BYTES (per-group total blob bytes). New group_quota env
helpers; count_rows/total_bytes repo methods (trait-default 0 for non-Postgres);
QuotaExceeded error variants on the three group error enums; a with_max_rows
test builder. Pinned by a group_kv_service unit test (3rd key rejected, update
of an existing key at the cap allowed).

Data layer for extending shared group collections from KV to docs. KV behavior
unchanged (callers pass kind="kv").
- 0054_group_docs.sql: widen the group_collections kind CHECK to ('kv','docs')
and add the group-keyed group_docs store (clone of docs/0013, keyed by
group_id, CASCADE on group delete) + its (group_id,collection) and data GIN
indexes.
- group_collection_repo: thread a `kind` parameter through list_for_owner,
resolve_owning_group, insert/delete_collection_tx; add list_all_for_owner ->
(name,kind) for the kind-aware diff (D4). Relocate the injectable
GroupCollectionResolver trait + Postgres impl here (now shared by kv+docs;
resolve takes kind) — was in group_kv_service.
- group_docs_repo: a near-clone of docs_repo keyed by group_id; find reuses the
generalized build_find_query.
- docs_repo: generalize build_find_query(table, owner_col, owner_id, …) — both
are compile-time literals (no injection); app docs passes ("docs","app_id"),
group docs ("group_docs","group_id"). row_to_doc/build_find_query are now
pub(crate) for reuse.
Schema snapshot re-blessed (55 migrations).
