bug: fix CI — drop Kover, cross-platform npm, de-flake matrix

Kover 0.9.1 reads the compileKotlinTask property removed in Kotlin 2.x, which
broke build/coverage config and the verify compile under the IntelliJ Platform
plugin's compilation model. Remove Kover (coverage of this thin adapter is
low-value; JaCoCo can return later if wanted). Also: launch npm via npm.cmd on
Windows so the server-bundling task works there, switch tasks.registering to
tasks.register (Gradle 9.6 deprecation), set fail-fast: false on the matrix,
and raise the Gradle heap. Clean no-cache build passes locally.
