In `@package.json`:
- Line 91: Update the PR/commit message and package metadata to document why
pnpm was bumped to "pnpm@11.6.0" (security/critical fix), referencing the
affected artifacts (package.json change to "packageManager": "pnpm@11.6.0",
pnpm-lock.yaml entry, and CI using pnpm via pnpm/action-setup) and note that
engines.node targets 24.x; explicitly state that the bump addresses
GHSA-3qhv-2rgh-x77r (project-level env var expansion restriction) so reviewers
and auditors understand the security rationale.
