chore(release): 0.1.3

[alexmc2]

Prepare 0.1.3 release with README badge cache refresh and changelog update.

• Update README npm badge URL to include cache-busting query param (?cb=0.1.3) so GitHub/npm renders the latest version badge.
• Add CHANGELOG entry for 0.1.3 documenting the badge refresh fix.
• Bump package metadata to 0.1.3 for release alignment.
• Keeps release flow tag-driven (push v0.1.3 to trigger publish workflow).
