…verage PR astral-sh#18451 changed `artifact_environments` from only `required_environments` to `supported_environments + required_environments`, causing `tool.uv.environments` to enforce artifact coverage. This breaks packages like flashinfer-jit-cache that provide platform-specific wheels from custom indexes when the environment can't be forked further. Split `artifact_environments` into separate `supported_environments` and `required_environments` fields. For `supported_environments` (from `tool.uv.environments`), fork when possible but skip when forking fails. For `required_environments` (from `tool.uv.required-environments`), keep the existing behavior of erroring when forking fails. URL dependencies continue to enforce coverage for both supported and required environments since they are explicit pinned files. Fixes astral-sh#18527 https://claude.ai/code/session_01DHYzoSf5k4hoWSNgKCSj9y
