v0.4.0

Prebuilt Linux x86_64 and arm64 NTS extensions, named for PIE's prebuilt-binary download, for PHP 8.3, 8.4 and 8.5 on Debian Bookworm, with the source archive. Each binary archive carries its own manifest.json recording the exact ABI it was built and tested against.

phit 0.4.0 renames the model functions; the 0.3 names remain as deprecated aliases until 0.5. Numerical results do not change. See the migration table in CHANGELOG.md.
