Merge Risk: Low · previous review 64f71

C API builds can fail on Windows GNU and 32-bit MSVC targets. These are bounded compatibility issues outside the demonstrated CI targets; address them or explicitly accept those target limitations before merging.

Pre-merge checks: 5

Check name	Status	Explanation
Description Check		Check skipped - CodeRabbit’s high-level summary is enabled.
Title check		The title clearly describes the primary change: enabling the capi feature for CPython test builds. The workflow, cache, linker, and export changes support this objective.
Docstring Coverage		Docstring coverage is inconclusive: files from earlier reviews still need to be rechecked within the check's analysis limits. Not blocking.
Linked Issues check		Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check		Check skipped because no linked issues were found for this pull request.
