- add 'kimi' to CLIProxyProvider union type
- register Kimi capabilities (device_code flow, moonshot alias)
- add OAuth config, auth prefixes, type values, channel maps
- add CLIProxy-delegated token refresh for Kimi
- add Kimi model catalog (k2.5, k2-thinking, k2)
- switch base-kimi.settings.json to CLIProxy mode (127.0.0.1:8317)
- update comments removing kimi from settings-based profile mentions
