doc: capnproto instruction for Alpine and Arch
What changed, and why it matters
This commit only updates documentation for building Bitcoin Core on Alpine and Arch Linux. It adds instructions to install the Cap'n Proto library, which is needed for a new optional inter-process communication (IPC) feature, and mentions how to disable that feature if not needed. There are no code changes and no security fix or vulnerability introduced.
No security action needed. Treat as routine documentation update.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff modifies doc/build-unix.md only. It adds Alpine package install commands for capnproto and capnproto-dev, notes the -DENABLE_IPC=OFF cmake option, and adds capnproto to the Arch Linux pacman dependency list. No source code, build scripts, or configuration logic are changed.
