fix(cicd): label build artifacts as dank-mids outputs

[BobTheBuidler]

Motivation

• The build artifacts produced during the mypyc runs are outputs of the dank-mids library (which vendors aiolimiter), so artifact names and download patterns should reference dank-mids rather than the vendored package.
• This clarifies ownership of compiled wheels and C/H sources and avoids confusion when publishing or diff-checking generated sources.

Description

• Renamed artifact upload/download labels and patterns in .github/workflows/build.yaml from aiolimiter-* to dank-mids-* and updated the Linux C/H artifact name to dank-mids-linux-c-headers.
• Kept artifact paths pointing at the vendored location dank_mids/_vendor/aiolimiter/src/ so the build still collects the vendored extension outputs.
• No changes were made to the mypyc matrix strategy or gating logic for Linux C/H sources beyond relabeling artifacts.

Testing

• Ran PYTEST_DISABLE_PLUGIN_AUTOLOAD=1 pytest, which errored during collection due to a missing external executable (ganache-cli), so compiled-extension verification could not be completed.

Specify python-version in matrix include entries

The matrix.include entries only set os plus the artifact fields, but they omit python-version. In GitHub Actions, include data is only merged into a matrix job when it matches an existing combination, so these entries won’t apply to the 15 os+python-version jobs. That leaves matrix.artifact_suffix/matrix.artifact_glob empty in the upload step, producing artifact names like dank-mids--artifacts-3.10 and paths without the glob; the downstream download patterns (dank-mids-macos-artifacts-*, etc.) won’t match those names, so the finalize job will miss compiled binaries. Add python-version to each include row (or use a mapping expression) so every matrix combination gets the suffix/glob.
