Add standard-version as a devDependency and wire it into npm scripts for cutting releases.

Changes

• Add standard-version@^9.5.0 as a devDependency.
• Expose three release scripts in package.json:
  • npm run release — bump package.json, regenerate CHANGELOG.md, create the vX.Y.Z tag.
  • npm run release:dry — preview the bump, changelog, and tag without writing.
  • npm run release:first — tag the initial release without re-bumping.
• Document the release flow in the README.md (dry-run → release → push tag → npm publish), plus a short note on --release-as for forcing a specific SemVer bump.
• No config file is added; standard-version's defaults fit this project (single package.json as the bump file, GitHub commit URLs inferred from repository.url, vX.Y.Z tag prefix).

Verification

• npm run release:dry runs cleanly and correctly infers the Conventional Commits preset and the next bump from the current commit history.
• pre-commit (eslint + npm test) and commit-msg (commitlint) hooks pass on the integration commit.

Notes

• No CHANGELOG.md is generated or committed by this PR — the first entry will be produced by whoever runs the first npm run release after this is merged.
• The project also lacks a GitHub Actions workflow to publish on tag push; happy to add that in a follow-up if you want releases to flow end-to-end.
