beta/3.14.0 regressed PortaPy native_api.py into constant-zero stubs

[deltathedumb]

Regression

Compiling PortaPy's unchanged src/portapy/native_api.py from deltathedumb/portapy produced materially different assembly across two CI runs.

Known-good compiler tree:

• 376cf9422c28123673a1dedd7dd66b845f3c5ed1
• portapy_abi_version() emits mov rax, 1
• Linux and Windows external C conformance hosts pass

Current beta/3.14.0 behavior observed after the branch moved:

• the same PortaPy source SHA 5ff01e067207957d2f05bcc4655fd2882d66963f0b8f883f40768bb82d8d33bc compiles public/native helper functions into constant-zero stubs
• example generated body:

portapy_abi_version:
    push rbp
    mov rbp, rsp
    mov rax, 0
    jmp .Lret_portapy_abi_version_25

• the resulting shared library links, but the external host exits because ABI version is 0
• generated library size dropped from roughly 142 KB to 74 KB for identical source

PortaPy is temporarily pinning the known-good compiler SHA for reproducible builds. Please add src/portapy/native_api.py as a compiler regression target and restore full function-body emission on beta/3.14.0.
