use slimmer docker image

[aradwann]

improvements:
Layer Reduction: Combined RUN commands where appropriate.
Smaller Base Image: Used bookworm-slim as the base to reduce image size.
Removed Unnecessary Packages: Used --no-install-recommends to install only necessary packages, avoiding bloated images.

might help a little bit in resolving #7

Thanks for your contribution! This looks great

actually, i can see that the linker script for musl compilation is no longer present. is this deliberate? does this still work for musl builds?

after reorganising the dockerfile I wanted to see if it would work without linking the licstdc++, but there is no pipeline here to verify, so I restored it

[jackkleeman]

nice! I'll merge and check if a binary build still works over in the main repo

[aradwann]

GH in this repo

before

after

that's a good sign!

[jackkleeman]

haha, thats actually because we updated the docker.yml over in the main repo to use a much beefier actions runner

OK, i had to add build-essential but otherwise seems to work. thanks again
