chore(sprint-13/W-I1): D-CSV-13b — commit Cargo.lock criterion entry

Orchestrator-only fix per autoattended-multiagent-pattern §5 Rule 3
(atomic consolidation pass). The retry worker added `criterion` as
a dev-dep in `crates/lance-graph-contract/Cargo.toml` (commit a356e64)
and successfully ran `cargo bench` locally — which silently
regenerated Cargo.lock — but never staged or committed Cargo.lock
itself. PR #398 as pushed has Cargo.toml expecting `criterion` while
Cargo.lock does not list it; any `cargo build --locked` (CI default)
fails with "the lock file Cargo.lock needs to be updated".

Adds the single missing entry under `[[package]]` for `lance-graph-contract`:
```
 dependencies = [
+ "criterion",
   "glob",
   "serde",
   "serde_yaml",
```

No semantic changes to lance-graph-contract or any other crate. The
criterion package itself was already pulled in as a transitive of
other workspace members, so this commit adds only the dep reference,
not a new crate version.
