Unblock npm publish by advancing package version past 5.0.0 (#35)

The previous publish attempt failed because version 5.0.0 already exists on npm.
This bumps @imdeadpool/guardex to 5.0.1 in both manifest and lockfile so release
can proceed without overwriting an immutable published version.

Constraint: npm does not allow re-publishing an existing version
Rejected: Force-publish 5.0.0 again | npm rejects immutable version reuse
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep package.json and package-lock.json version fields aligned for each release bump
Tested: npm test (54/54)
Not-tested: Live npm publish for 5.0.1 in this commit step
