Bat pulls in the onig crate (version 6.4.0) through syntect with the default "regex-onig" feature. This crate depends on the Oniguruma C library (via onig_sys), which fails to build with GCC 15 due to C23 keyword conflicts. Newer versions of onig fix this issue, but bat cannot directly update the onig version because it is pinned by syntect. To resolve the build failure, apply a patch that replaces the "regex-onig" feature with "regex-fancy" in bat's minimal-application feature set. This switches bat to use the pure-Rust fancy-regex engine instead of Oniguruma, avoiding the problematic onig_sys dependency.
