/**
* Patched jackson-core forced onto Dokka's classpaths.
*
* Dokka 2.x pulls jackson-core transitively (dokka-core -> jackson-dataformat-xml / -module-kotlin),
* and the 2.15.x line it selects is vulnerable to GHSA-r7wm-3cxj-wff9 (async-parser `maxNumberLength`
* bypass, CWE-770). Dokka is a build-time-only documentation tool, so this never ships in the app, but
* pinning the patched line keeps the resolved dependency graph clean and closes the Dependabot alert.
* 2.18.8 is the first patched release and the closest maintenance line to Dokka's transitive 2.15.3.
