feat(clickhouse): tracked archive→CH backfill tooling (backfill.sql)

When a model has accumulated many data artifacts that need removing (e.g. a batch of orphaned per-run scratch artifacts, or a deprecated data-name family), the only tool today is swamp data delete <model> <name>, which removes one artifact at a time. Each call acquires the datastore lock and does a full index sync, so removing N artifacts means N separate lock acquisitions.

On a high-churn shared datastore that's self-defeating: clearing a backlog of (in our case) ~2,500 artifacts via 2,500 sequential data delete calls would contend on the very namespace lock the cleanup is meant to relieve, and at ~60–90s per lock-hold it isn't practically completable. GC doesn't help here because the artifacts aren't expired (separate ripple on #823 re: ephemeral collection), and deleting them directly from object storage behind the datastore's index risks leaving the catalog and backing store inconsistent.

Proposed solution

A batch/bulk delete on swamp data delete that performs the removal in a single lock acquisition + single index sync, e.g. one of:

swamp data delete <model> --prefix <str> — delete all data-names starting with a prefix.
swamp data delete <model> --glob '<pattern>' — glob match on data-name.
swamp data delete <model> --names a,b,c / --names-file <file> — explicit batch list.

A --dry-run (listing what would be removed) and confirmation gate would match the existing data gc ergonomics.

Alternatives considered

Looping swamp data delete per name — the status quo; lock contention makes it impractical at scale.
A model-side cleanup method — not currently possible: the model-method dataRepository context exposes findAllForModel / getContent / listVersions but no delete primitive.
Direct object-store deletion — bypasses the index and risks catalog/store divergence.

This generalizes beyond our case — any at-scale user accumulating per-run artifacts hits the same "how do I clear a family of data-names without N lock acquisitions" wall. Totally understand if it's out of scope or better folded into auto-GC; appreciate the consideration either way.
