Development (#172)

* docs: Add CLAUDE_RULES.md with strict rebrand protection rules

- Define immutable rebrand rules that cannot be violated
- Prohibit reverting rebrand for cargo check convenience
- Establish checkpoint and audit trail requirements
- Document correct error handling approach

* refactor: Complete kurdistan-sdk to pezkuwi-sdk rebrand

- Update README.md with pezkuwi-sdk branding
- Replace all kurdistan-sdk URL references with pezkuwi-sdk
- Replace kurdistan-tech with pezkuwichain in workflows
- Update email domains from @kurdistan-tech.io to @pezkuwichain.io
- Rename tool references: kurdistan-tech-publish → pezkuwi-publish
- Update runner names: kurdistan-tech-* → pezkuwichain-*
- Update analytics/forum/matrix domains to pezkuwichain.io
- Keep 'Kurdistan Tech Institute' as organization name
- Keep tech@kurdistan.gov as official government contact
