xarmian 1b1068537c feat(tags): workspace tag enumeration endpoint + cross-collection filter (TASK-1653) (#658)
* feat(tags): workspace tag enumeration endpoint + cross-collection filter (TASK-1653)

Foundation for the tags feature (PLAN-1652 / IDEA-1649). The write path and
per-collection ?tag= filter already existed; this adds tag enumeration and a
verified cross-collection read so a single tag can group items of any type.

- store: dialect.JSONArrayElements unnests a JSON text-array column
  (json_each on SQLite, jsonb_array_elements_text on Postgres);
  Store.ListWorkspaceTags returns distinct tags + item counts, ordered by
  count desc then tag asc, with the same collection/item ACL filters as
  ListItems so counts never leak hidden items.
- server: GET /workspaces/{ws}/tags (handleListTags), respecting collection
  visibility + guest item grants.
- models: TagCount{tag,count}.
- cli: client.ListTags + `pad tag list`.
- web: api.tags.list + TagCount type (items.list already forwards `tag`).
- tests: store-level (cross-collection aggregation, collection scoping,
  non-nil-empty = empty, archived excluded) and handler-level (a Task + an
  Idea sharing one tag; GET /tags counts + ordering).

Parent: PLAN-1652.

* fix(tags): count distinct items per tag, not tag occurrences per Codex review (round 1)

COUNT(DISTINCT i.id) so an item with duplicate tags (e.g. ["ux","ux"]) is
counted once — the write path doesn't enforce per-item tag uniqueness.
Adds a regression test.
