Closes #888

Summary

  • Make speculative queues and terminal shutdown safe under detach races.
  • Release probe-owned MBeans with token-checked cleanup, and make terminal runtime exit deliver one ordered marker and Exit command.
  • Surface isolated event/error handler failures without corrupting runtime state.
  • Harden profiler snapshot/deferred-record coordination and prune cleared recorder references.
  • Normalize probe class-definition failures across runtime tiers.

Verification

  • :btrace-runtime:test
  • :btrace-agent:test
  • :btrace-dist:build
  • :btrace-compiler:test --tests io.btrace.compiler.BTraceDslVerifierTest
  • Focused Issue888RuntimeHardeningIntegrationTest
  • Full -Pintegration :integration-tests:test
  • Scoped Spotless checks and git diff --check
