chore(deps): roll up Dependabot updates (#1101)

## Summary

Roll up the remaining dependency changes from eight open Dependabot PRs
against current `main`, without reverting newer workflow settings:

- CodeQL init, analyze, and autobuild: 4.37.7 → 4.38.1 (#1097, #1096,
#1095)
- zizmor-action: 0.6.3 → 0.6.4 (#1085)
- @biomejs/biome: 2.5.9 → 2.5.11, including its schema URL (#1075)
- @types/node: 26.2.0 → 26.4.0 (#1074)
- Jest: 30.4.2 → 30.5.0 (#1073)
- js-yaml: 5.3.0 → 5.4.1 (#1072)

All nine open Dependabot PRs had remaining dependency changes; none was
a no-op. TypeScript 7.0.2 (#1029) is intentionally deferred with
maintainer approval: ts-jest 29.4.11 requires TypeScript <7, and
applying the update caused all 15 test suites to fail before running
with `Cannot read properties of undefined (reading 'readFile')`.

The lockfile was regenerated using npm install with scripts disabled. No
runtime dependency entries changed, and repackaging produced no `dist/`
changes.

## Validation

Using Node 24.19.0 and npm 11.10.0:

- `npm ci --ignore-scripts`
- `npm run all` — passed; 15 test suites, 159 tests; Biome applied no
fixes
- `npm audit signatures` — all 353 audited packages have verified
registry signatures; 38 have verified attestations
- `actionlint .github/workflows/codeql-analysis.yml
.github/workflows/test.yml` — passed
- `uvx zizmor --no-progress --offline
.github/workflows/codeql-analysis.yml .github/workflows/test.yml` — no
findings
- `git diff --check` — passed
