Backup-orchestration commands were split across two namespaces (pull in
agnes store, push in agnes admin store), which broke the operator
mental model — pull/push are a paired operation and should sit
together.
Move pull + info into agnes admin store so all bulk operations share
one help screen. Add agnes store mine as the user-facing equivalent —
calls the same /api/store/bundle.zip endpoint with ?owner=me, which
the server resolves to the caller's user_id. Authors can archive
their own uploads without admin role; whole-Store bulk reads stay
admin-flavored as a discoverability hint.
Server: 3-line addition to export_bundle handles owner='me' as a
magic alias for the caller. No new endpoint.
Tests updated: pull/info expectations move from agnes store to
agnes admin store; new tests cover agnes store mine and the
?owner=me server resolution. 69/69 store tests green locally.
