Codewhale review

This Dependabot PR updates the schemaui crate from 0.12.3 to 0.12.4 in Cargo.lock. The upstream release is a patch-level bug fix that omits null-valued objects in TOML preview output, plus documentation/CI housekeeping. No new dependencies are introduced and no code changes are included in the PR.

Findings

• [INFO] Only Cargo.lock was updated; confirm manifest version constraint (Cargo.toml)
  The diff does not include a Cargo.toml change. If schemaui is a direct dependency, verify that its declared version requirement still permits 0.12.4 (e.g. "0.12" or "0.12.3" with caret semantics). If the project intentionally pins the exact version, Cargo.toml should also be updated.
• [WARNING] TOML preview output may change
  schemaui 0.12.4 includes a bug fix that omits object nulls in TOML preview. If CodeWhale uses schemaui's preview functionality, rendered output may change for configurations that previously included null-valued objects. Existing snapshot or golden-file tests may need to be updated, and the new behavior should be verified as intended.

Suggestions

• Run the full test suite, especially any tests covering schemaui or TOML preview snapshots, before merging this dependency bump.
• Cargo.toml — If schemaui is a direct dependency, consider making the minimum version explicit by updating the requirement to "0.12.4" or "^0.12.4".
• Add or update a regression test for TOML preview with null object fields to document the new omission behavior and prevent accidental regressions.

Assessment

Low-risk patch-level dependency bump. No blocking issues found, but the TOML preview behavior change should be verified against existing tests before merging.

Maintainer note: both reds on this PR (Test macos-latest and Test windows-latest, run 33270725867) are the six sandbox::read_guard tests plus root_parent_traversal_does_not_escape_above_root — the pre-#5724 baseline on 20e957406, not anything in this bump. #5724 (merge 8a3f14bf8) fixed exactly that set on main, and main's latest completed CI run (33324284899 on 977a647bd) has the full Test matrix green. The bump itself is Cargo.lock-only, and schemaui 0.12.4 still pins jsonschema ^0.46, so it stays in step with the workspace pin in Cargo.toml. Rebasing onto current main should clear both legs; will merge on green.
