create/update on embeddable repos enqueue embed.text with a singleton
key that coalesces rapid edits. No-op when the queue is not running
(server tests construct createApp without booting pg-boss).

Pads nomic-embed-text's 768 dims to 1024 zeros so a later 1024-dim model
swap is a re-embed, not a migration (per master spec).

Job queue starts only in the CLI gate (not inside createApp), so tests
manage their own queue lifecycle. waitForJob() takes a (name, id) pair
to match pg-boss v10's getJobById signature.

Per-name ensureQueue promise dedup so concurrent enqueue+subscribe
on the same queue do not race createQueue (Postgres deadlock).
