reload: drain microtasks after reloadEntryPoint so out-of-tick() callers progress

ci: retrigger (flake on test-http-should-emit-close + hot-sourcemap)

ci: retrigger (hot.test.ts sourcemap is a documented cross-PR flake)

ci: retrigger (BuildKite agent creation failures — fleet issue)

ci: retrigger (fleet-wide flakes, see also #30250/30257/30258/30262/30263/30266/30267)

reportException: tail-recurse after reload() to see the fresh promise

ci: retrigger (13 buildkite agents expired on build 51653)

ci: retrigger (test-http-should-emit-close — ~100% flake on main, see #30217)

comment: refer to the local `promise` by name, not line number

ci: retrigger (11 cpp-build lanes expired — fleet outage, see also #30275/30278)

onBeforeExit: drain microtasks after dispatch so TLA continuations complete

Revert onBeforeExit microtask drain — breaks test-event-capture-rejections
