fix: regenerate lock file to resolve npm audit vulnerabilities

[cs-raj]

Problem

The committed lock file pins vulnerable transitive versions: npm audit reports 42 findings on master (1 critical, 33 high). Snyk reports 0 on the production tree. This is a LIBRARY, so consumers resolve our package.json ranges themselves and this lock file only affects our own dev/CI install.

Fix

• Regenerated package-lock.json (fixes 5 npm audit findings with no manifest change, including the critical).
• No direct bump or override added: none of the patch/minor bumps clears a finding, and the remaining findings need majors.
• Package version 1.5.3 -> 1.5.4.
• Remaining npm audit findings (37, all dev-only via jest, ts-jest, @types/jest, node-notifier) need major bumps (jest 30, node-notifier 11), left for a separate change.

Verified: npm run build-ts passes; Snyk 0 -> 0, npm audit 42 -> 37.

Closing: this only regenerated the lock file and bumped the version, and no Snyk finding changes (0 before, 0 after). Not needed.
