/**
 * hosts.ts, the real effects behind the trigger family's ports.
 *
 * manager.ts holds the policy and takes every effect as an injected port, so
 * this file is the one place where that policy meets an actual subprocess and
 * an actual agent. A host wires these once at composition; tests keep using
 * fakes.
 *
 * The on-exit host is deliberately built on ProcessManager rather than a fresh
 * Bun.spawn: ProcessManager already owns the credential-env scrub, the live
 * output collection, the SIGTERM→SIGKILL watchdog and the terminating-signal
 * capture, every one of which an honest termination payload needs. Building a
 * second, thinner spawn path here would mean an on-exit trigger silently had
 * weaker guarantees than a plain background command.
