The package and npm registry were both at 5.0.4, so publishing would conflict. This bumps the package to 5.0.5 and records the matching release-note entry so publish workflow and metadata checks stay aligned.

Constraint: Keep README release notes in sync with package version for metadata guardrails

Rejected: Publish 5.0.4 again | npm rejects duplicate published versions

Confidence: high

Scope-risk: narrow

Reversibility: clean

Directive: For every future version bump, update README release notes in the same change

Tested: npm test

Tested: npm pack --dry-run
