teknium1 19c8ad3d3d fix: add Claude Code user-agent to OAuth token exchange/refresh requests ...

Anthropic's token endpoint is behind Cloudflare which blocks Python's
default urllib user-agent (Python-urllib/3.x). Without a proper
user-agent, the token exchange returns 403 (Cloudflare error 1010).

Adds 'claude-cli/2.1.2 (external, cli)' user-agent to all three
OAuth HTTP requests:
- Initial token exchange (authorization_code grant)
- Hermes token refresh (refresh_token grant)
- Claude Code credential refresh (refresh_token grant)

Verified: full OAuth PKCE flow now works end-to-end.
