* feat(tools): implement image reference processing and native provider support
- Support OpenAI image edits via both Multipart form-data and JSON payloads
- Automatically append reference image descriptions to prompt under [Reference Image Roles]
- Support downloading image URLs for Gemini native image generation
- Deduplicate reference images to optimize API request size
- Add unit tests for Codex, DashScope, MiniMax, BytePlus and local/remote path resolution
* fix(tools): SSRF-guard reference-image URL downloads in create_image
downloadImageBytes fetched caller-supplied ref_images[].url with a plain
http.Client and unbounded io.ReadAll — no SSRF validation, redirect
policy, or size cap, letting the gateway dial loopback/private/metadata
hosts or read arbitrarily large responses.
- Validate the URL via security.Validate and pin the resolved IP, then
download through security.NewSafeClient (pinned dial, no redirects).
- Cap the response with a bounded read (refImageMaxBytes, 20 MB).
- Reject non-HTTP(S) reference URLs up front (file://, data:, gopher://)
so provider-forwarded URLs stay HTTP(S)-only; document the trust
boundary between gateway-side fetch and provider-forwarded URLs.
- Add regression tests: blocked loopback/private/metadata, unfollowed
redirect, oversized response, and non-http(s) scheme rejection.
- Update go.mod and Dockerfile to Go 1.26
- Apply `go fix ./...` stdlib modernizations across 170+ files
- Add `go fix` to post-implementation checklist in CLAUDE.md
- Fix go fix misapplied rewrite in loop_history.go
Refactor create_image and create_video to use a shared provider chain system.
Each tool now supports an ordered list of providers with per-entry timeout,
max retries, and provider-specific params. Includes MiniMax and DashScope
image/video generation implementations.
- New media_provider_chain.go: shared chain resolution, retry execution, limitedReadAll
- create_image: refactored to ExecuteWithChain, added MiniMax + DashScope providers
- create_video: refactored to ExecuteWithChain, added MiniMax async video generation
- Backward compatible with legacy {provider, model} settings format
