CPython 3.14 for slicc WASIX (commands python / python3).

Features

• PIE dynamic-main (dylink.0), SOABI cpython-314-wasm32-wasix
• No fork/vfork; subprocess via os.posix_spawn (proc_spawn2/3)
• mmap builtin via -D_WASI_EMULATED_MMAN + -lwasi-emulated-mman (mmap/munmap/msync; no madvise/mprotect)
• Bundled pip (ensurepip wheel) + tomllib / xmlrpc for pip’s import graph
• zlib for gzip (dateutil zoneinfo, etc.)
• static _bz2 / _lzma, sqlite3, readline (+ termcap shim)
• pwd/grp/fcntl/termios/resource builtins
• getuid/geteuid/getgid/getegid → 1000 via --wrap stubs; passwd-less pwd/grp → user/1000//home/user
• Advisory file locks (flock / fcntl F_SETLK* / lockf) are no-ops in the SLICC realm (Emscripten parity).
• stdout is line-buffered unless it is a regular file, so output streams and survives crashes
• 3.14.2-8 is identical to accepted 3.14.2-7 (npm phantom-staged -7 blocked republish; see npm/cli#9889).
• PRESTAGE: prestage-check.sh blocks stage unless SOABI wasix + wrap-getuid=1000
• wasix-libc setitimer/alarm patch: calls proc_raise_interval2 with both it_value and it_interval (legacy proc_raise_interval untouched; see patches/)

Acceptance (Wasmer / SLICC)

python -c "import mmap; print('mmap ok')"
python -m pip install --prefix <dir> six   # SLICC: HTTPS via realm proxy + SSL_CERT_FILE
PYTHONPATH=<dir>/lib/python3.14/site-packages python -c "import six"

On plain Wasmer without _ssl, use a local wheel (--no-index --find-links) until openssl/_ssl is enabled.
