iregexp-check: Add version 0.1.4

[luhenry]

• Package: iregexp-check
• Version: 0.1.4
• Source: https://github.com/jg-rp/rust-iregexp
• Docs: https://github.com/jg-rp/rust-iregexp/tree/main/crates/python

Compiles a small PyO3/maturin extension that checks I-Regexp (RFC 9485) patterns. Upstream publishes no riscv64 wheel.

Mirrors upstream's pypi_release.yml linux job.

Differs from upstream

• Bumped the crate's unconditional abi3-py38 pyo3 feature to abi3-py39 (patch) - the riscv64 manylinux image's oldest interpreter is cp39, no cp38.
• Dropped musllinux - rustup ships no riscv64 musl toolchain.

Matrix: single cp39-abi3 leg - upstream ships no free-threaded wheel for 0.1.4, and the pinned pyo3 0.22 predates Py_GIL_DISABLED entirely.

Testing

• Upstream ships no Python test suite; the RFC 9485 valid/invalid patterns from crates/iregexp's own Rust test suite (plus the README examples) are run as a smoke test instead.

License: OK.

Patches

• 0001-python-bump-abi3-floor-to-py39.patch - Inappropriate [manylinux_2_39_riscv64 ships no cp38 interpreter]. Without it the wheel would claim a cp38 floor never actually built or tested on. Reproduces on any host, not riscv64-only.

Built on cp39 (rehearsed locally on x86_64, plus a riscv64 cross cargo check); 17 assertions passed, 0 skipped.
