Add the synchronous openai_image host protocol so a task plugin can claim
POST /v1/images/generations and /v1/images/edits; the host submits the
task, polls it inside the request and lets the plugin render the OpenAI
image response. Unclaimed models still fall back to the HTTP image relay.
- Migrate Ali (Bailian) image models to the alibaba plugin and remove the
ali channel image/wan adaptors and the qwen model setting
- Add Doubao Seedream image generation to the doubao plugin
- Support retainResult on routes and indexed multipart file references
- Settle image counts from upstream usage or image payloads; document the
rule in the billing conventions and plugin API docs
- Show billing source and task artifacts in usage logs; rename the
DoubaoVideo channel display name to Doubao and refresh the favicon
Group sensitive-word checks, channel selection, retries and channel health
under one "Request policies" settings area with a session rules editor,
per-rule session modes (inherit/off/prefer/strict) and a global default.
Record routing decisions per attempt into log admin info, expose
GET/PATCH /api/option/request_policy with whole-policy validation, and
redirect the legacy settings URLs to the new sections.
