CI: Don't do release target build, create "small" profile
Using RUST_TARGET=release is slower than RUST_TARGET=debug, *but*
the images are much bigger.
On my laptop, but restricted to 4 CPUs. I added a target to build all
the prerequisited but not compress the bzip2:
RUST_TARGET Time to build Size (testpack.tar.bz2)
release 4m49s 133MB
debug 2m34s 343MB
small 2m9s 155MB

What changed, and why it matters
This commit changes the project's automated build settings to use a new 'small' Rust compilation profile instead of the 'release' profile. The goal is to make CI builds faster and produce smaller artifacts for testing, with no intended functional change to the software itself.
No security action required. This is a CI/build optimization change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch adds a new Cargo profile named ‘small’ that inherits from the ‘dev’ profile with opt-level=0, debug=0, and codegen-units=32. It then updates GitHub Actions CI workflows to use RUST_PROFILE=small instead of RUST_PROFILE=release. The commit message explains this trades off optimization for faster builds and smaller testpack artifacts compared to debug builds.
