Generate release with changelog

Bump version, generate changelog, tag, and push release to main

Automating SemVer version bumps and changelog generation when releasing to production

• · package.json (current version)
• · commit history since last tag

• · git tag
• · git push to origin main with tags
• · new version number

• · npm run release:*
• · git

• · on main branch
• · working directory clean
• · npm scripts defined (release, release:dry, release:patch, etc)

• · npm run release:dry fails to detect version
• · user cancels after dry run
• · git push fails (no perms)

• · Dry-run preview before commit
• · explicit user confirmation step
• · four bump strategy options (auto/patch/minor/major)
