Disable multiprocessing when building Bitcoin Core
Some dependencies are missing for multiprocess, and it's anyway
not useful in CI.
What changed, and why it matters
This commit changes a CI Dockerfile used to build Bitcoin Core for testing. It adds a build flag that disables Bitcoin Core's optional multiprocessing (IPC) feature because the build environment lacks the required dependencies. This is a build-configuration convenience change, not a security fix for the Ledger app itself.
No security action needed. Treat as a routine CI/build maintenance change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
In .github/workflows/Dockerfile, the Bitcoin Core build command was changed from cmake -B build to cmake -B build -DENABLE_IPC=OFF. This disables the bitcoin-node/bitcoin-gui multiprocess executables, which require libmultiprocess/capnp dependencies not installed in this Docker image. The change avoids a build failure in CI and has no effect on the Ledger Bitcoin app firmware or its runtime security.
