chore(repo): prepare Samva public repository move

[aryasaatvik]

Summary

• Present this public repository as Samva while retaining its packages, examples, cookbooks, and agent plugins.
• Point package metadata, plugin manifests, release documentation, and Tegami GitHub publishing configuration at SamvaHQ/samva.
• Rename the private workspace identity to samva and preserve the private core repository as the plugin provenance source.
• Keep .github/workflows/publish.yml unchanged because npm trusted publishing depends on that workflow filename.

Validation

• bun run release:check passed.
• bun run validate:agent-plugin passed.
• Release checks completed with two existing no-await-in-loop warnings in the Supabase example.
• git diff --check and formatting checks passed.

This PR prepares the repository for the post-merge transfer and rename. It does not perform the transfer, reconfigure npm trusted publishers, or deploy anything.
