build: limit Bouncy Castle alignment to -jdk18on modules

The resolution rule also rewrote the legacy -jdk15on artifacts that
metalava's tooling depends on to 1.86, a version that line never had
(it ended at 1.70), so metalavaCheckCompatibilityRelease failed to
resolve in CI. Only align the -jdk18on modules the app ships.

Add the metalava check to the pre-commit command in AGENTS.md so local
runs cover the same tasks as CI.
