fix(providers): remove the duplicate qwen provider

qwen.js points at the same transport as alims-intl — identical baseUrl
(dashscope-intl compatible-mode), headers, and quirks — but carries only 8
Qwen models against alims-intl's broader catalog, so it adds nothing a user
could not already reach. Node count is back to 81.

The id was dropped on 2026-08-05 (dcdd4628b) when the Qwen OAuth flow died;
this removes the standalone API-key entry that shadowed it. The `qw` alias
returns to unassigned, its state before today.
