fix(deps): resolve gpu/benchmarks extras conflict for uv

[FabianHofmann]

Since #909, uv lock/uv sync fail for everyone on master. This unblocks the dev environment again.

Note

The following content was generated by AI.

Problem

#909 added cuopt-cu12>=26.8 to the gpu extra. It pulls cudf-cu12, which pins pandas>=3.0.0,<3.0.4a0. The benchmarks extra pins pandas==3.0.5. The two are mutually incompatible, and the dev resolution requires both, so uv resolution is unsatisfiable:

Because cudf-cu12>=26.8.0 depends on pandas>=3.0.0,<3.0.4a0 ...
And because linopy[benchmarks] depends on pandas==3.0.5, we can
conclude that linopy[benchmarks] and linopy[gpu] are incompatible.
And because your project requires linopy[benchmarks] and linopy[gpu], we
can conclude that your project's requirements are unsatisfiable.

Fix

Declare the two extras as conflicting so uv resolves them in separate forks instead of unifying them:

[tool.uv]
conflicts = [[{ extra = "gpu" }, { extra = "benchmarks" }]]

After this, uv lock resolves (263 packages), uv lock --check passes, and uv sync --extra dev works. gpu and benchmarks remain individually installable but not together, which reflects the underlying pandas incompatibility.
