guix: use GCC 14.3.0 over 13.3.0
This will eventually be needed for #25573, and could be useful
for #30210.
What changed, and why it matters
This commit updates the Bitcoin Core build system to use a newer version of the GCC compiler (14.3.0 instead of 13.3.0) for its reproducible Guix builds. There is no security-relevant code change here; it is a routine toolchain version bump.
No security action needed. Treat as a normal build-system maintenance update.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change modifies contrib/guix/manifest.scm to define base-gcc from gcc-14 (with a custom 14.3.0 source tarball and verified SHA256 hash) and updates references from gcc-toolchain-13 to gcc-toolchain-14. This is a build dependency update in preparation for future work referenced by issue numbers #25573 and #30210.
