folk-runtime-embed 0.1.15

# Dockerfile for building and testing folk-runtime-embed.
#
# PHP is compiled from source with --enable-embed to produce libphp.so.
# Then Rust crate is built and tested against it.
#
# Usage:
#   docker build -f crates/folk-runtime-embed/Dockerfile -t folk-embed-test .
#   docker run --rm folk-embed-test
#
# Build context: folk-core root (so we can access all workspace crates)
