chore: remove NIP-C7 references from docs and code

- Remove nip-c7 from ChatProtocol type
- Remove commented NIP-C7 adapter imports and switch cases
- Update comments to reference NIP-29 instead of NIP-C7
- Update kind 9 renderer docs to reference NIP-29
- Clean up chat-parser docs and error messages
