feat(devin): add Devin/Cognition provider integration and CLI OAuth
Implement the full Devin/Cognition Connect-RPC provider support across all CPA endpoints (/v1/chat/completions, /v1/messages, /v1/responses), complete with binary protobuf wire framing, streaming tools/arguments delta handling, thinking/reasoning replay, and CLI OAuth authentication.
Key highlights:
- Wire Protocol & Streaming:
* Implemented Connect-RPC uncompressed 5-byte framing (0x00 + 4-byte length + protobuf) for ApiServerService/GetChatMessage.
* Implemented Devin protobuf encoder/decoder in internal/runtime/executor/helps/devin_wire.go, including ClientMetadata, prompts, tools, completion_config, and multimodal image handling (Prompt Field #10).
* Stream frame consumption via interactions protocol, correctly mapping arguments_delta and tracking multiple sequential tool calls (currentToolCallActive).
* Streaming thought summary and sealed.v1 signature deltas targeting the thinking step.
- Model Registration & Thinking Clamping:
* Registered static fallback models in model_definitions.go (swe-2, claude-fable-5-1, gpt-6-astra, swe-1-7-lightning, glm-5-2, glm-5-3).
* Configured ThinkingSupport with discrete levels per model family.
* Implemented CPA-standard nearest-neighbor clamping for thinking levels (minimal/low -> medium, xhigh -> max for swe-2).
* Mapped thinking effort to Devin upstream model UID (e.g. swe-2-medium, swe-2-high, swe-2-max).
- Sensitive Words & System Prompt Sanitization:
* Added devin.sensitive-words configuration in internal/config/config_types.go and config.go, matching Antigravity conventions.
* Supported zero-width space (\u200b) obfuscation in prompts, tools, and system instructions via SensitiveWordMatcher.
* Stripped Claude Code billing headers (x-anthropic-billing-header:) and CLI identity signatures from system instructions and tool descriptions to avoid upstream content filter rejections.
- Signature Compatibility:
* Added SignatureProviderSWE = "swe" recognizing sealed.v1.* reasoning signatures in internal/signature/provider_compatibility.go.
* Propagated reasoning.encrypted_content on Responses API and thinking.signature on Messages API.
- Authentication:
* Implemented Devin PKCE OAuth flow with loopback callback server and headless manual token/code paste (--no-browser).
* Registered Devin authenticator in SDK and CLI (-devin-login flag).
* Integrated with management OAuth session endpoints and credentials manager.
