Subject: [PATCH 1/2] Raise Maven version floor to 3.9.9 and bump gated plugins

Bumps maven-enforcer-plugin, maven-compiler-plugin, and
gmavenplus-plugin, which were previously held back by a stale
requireMavenVersion floor pinned to jitpack.io's old default Maven.
3.9.9 is confirmed via JitPack build logs to be the highest version
it fetches and uses correctly as of 2026-09-06; 3.9.10 and above
failed.

Subject: [PATCH 2/2] Remove .sdkmanrc

JitPack has no project Maven Wrapper, and build logs confirm it
downloads and builds with whatever Maven version the pom's enforcer
rule requires on its own, so pinning Java/Maven for it separately via
SDKMAN is no longer necessary.
