Greptile Summary

This PR updates documentation for adding a new AI provider channel, correcting stale file references and expanding the workflow steps to match the current codebase structure.

• Agent workflow (.agent/rules/workflows/add-channel.md) is rewritten with precise file paths, line ranges, and function names that all verify against the current source code.
• Developer guide (English and Chinese) drops the stale reference to the removed constants.ts file, adds the correct config_channels.ts / config_providers.ts split, and renames buildChannel to the current buildChannelWithTransformer.

Confidence Score: 5/5

Documentation-only update; no runtime code changed.

All referenced file names, exported symbols, and line ranges were verified against the live codebase — buildChannelWithTransformer, defaultEndpointsForChannelType, CHANNEL_CONFIGS, PROVIDER_CONFIGS, channelTypeSchema, getAPIKeyProvider, and the field.Enum type block all exist exactly where the docs say they do.

No files require special attention.
