refactor: reorganize GitHub workflows with consistent naming convention

- Implement systematic naming convention using category prefixes
- Group workflows logically: ci-, pr-, release-, types-, i18n-
- Rename all 22 workflows for better organization and discoverability
- Update workflow cross-references and display names
- Add comprehensive README.md with naming guidelines and best practices

Key changes:
- CI workflows: ci-tests-e2e, ci-tests-unit, ci-tests-storybook, etc.
- PR automation: pr-backport, pr-claude-review, pr-playwright-snapshots
- Release management: release-version-bump, release-npm-types, etc.
- Type generation: types-registry-api, types-manager-api, etc.
- Internationalization: i18n-update-core, i18n-update-nodes, etc.
