Note linting errors from crates/openfang-runtime/src/drivers/copilot.rs that are not part of this change:

Thanks @joshuachong — Alibaba Dashscope as a provider is a welcome addition. Verified the base URL (https://coding-intl.dashscope.aliyuncs.com/v1) is the official Dashscope-international endpoint, Bearer auth via ALIBABA_CODING_PLAN_API_KEY matches their docs.

Before merge:

1. Clippy/lint fallout — your PR notes mention lint warnings in copilot.rs that are not from your changes. Rebase on current main (post-fix(deps): upgrade wasmtime 41->43 and rumqttc 0.24->0.25 to resolve active CVEs #1041 which also touched drivers) and run cargo clippy --workspace -- -D warnings locally. If the noise persists, flag it and I'll look.
2. Parallel-test flakiness — your driver tests use std::env::set_var / remove_var which race across cargo test threads. Either wrap with a serial_test attribute or use a Mutex<()> guard for the API-key env tests.
3. Doc/code model count sync — docs/providers.md lists ~62 models for Alibaba; please confirm builtin_models() returns exactly that number so the numbers don't drift.

Once those are in and CI is green, this is ready to merge.

Closing. This pattern matches PR #747 which was rejected for fabricated pricing and User-Agent spoofing for the same provider family. A clean Alibaba Coding submission needs: (1) verified per-token costs from the official pricing page, or /usr/bin/bash entries with a clear note that the plan is flat-rate; (2) no UA spoofing; (3) catalog wiring complete with tests. Resubmit when ready.
