feat: always rebuild local source

If `FFI_BUILD_FROM_SOURCE=1` is set, always rebuild from local source.

Change the scripts so that it is built within the `rust` directory
and not on a temporary directory that is different on every rebuild.
This way you get incremental builds if you make changes to the local
source (which is probably your intention if you build from source).

feat: make local builds incremental

If `FFI_BUILD_FROM_SOURCE=1` is set, always build in the same

This commit Changes the scripts so that it is built within the `rust`
directory and not on a temporary directory that is different on every
rebuild. This way you get incremental builds if you make changes to
the local source (which is probably your intention if you build from

feat: use debug formatting for error messages

When using `anyhow` there is a huge difference between the debug output
and the display output. The display output is only the most recent
message text. The debug output contains also all the causes of the error
including a backtrace.
