chore(security): resolve open npm audit and code scanning alerts (#31)

* build(deps): resolve npm audit advisories via in-range bumps

npm audit fix bumps js-yaml 4.3.0, linkify-it 5.0.2, liquidjs
10.27.2, and brace-expansion 1.1.16 to clear four high DoS
advisories. Eleventy build verified passing at 3.1.6.

The remaining brace-expansion advisory (GHSA-mh99-v99m-4gvg) has
no in-range fix: the patch exists only in 5.0.8, and
@11ty/recursive-copy pins an older minimatch. Exposure is
build-time only (glob patterns from our own config, never
untrusted input), so it is suppressed with justification in
.security-review/suppressions.json rather than forcing the
eleventy downgrade npm audit fix --force proposes. Remove the
npmaudit-* suppressions when recursive-copy ships a minimatch
>=10.0.3 bump.

* ci: add least-privilege permissions blocks to workflow callers
Resolves code scanning alert #3 (actions/missing-workflow-permissions). Callable workflow only needs contents: read; the dependency-review callable already declares it internally, this caps the caller token to match.

* ci(dependency-review): allow adjudicated brace-expansion GHSA

Re-pins the callable to 07ce007 (adds the allow-ghsas input, org
PR #89) and allows GHSA-mh99-v99m-4gvg, which the review check
flags on the bumped-but-still-in-range brace-expansion 1.1.16.
The advisory has no in-range fix and is an accepted risk with
written justification in .security-review/suppressions.json;
remove the allowance together with those suppressions when
@11ty/recursive-copy ships a minimatch >=10.0.3 bump.
