EventGate.dispose() does not clear sleepTimer

[Anarchid]

Noticed while probing EventGate during a slack-mcpl review (main 5498805 / v0.19.0).

setSleep arms this.sleepTimer = setTimeout(() => this.wakeFromSleep('sleep-expired'), ms) (src/gate/event-gate.ts ~1663) without unref. dispose() (~1919-1935) clears debounceTimers and selfWakeTimers but never sleepTimer. Probe after dispose(): remainingTimer=true, hasRef=true — the timer keeps the process alive and later fires wakeFromSleep on a disposed gate.

Fix: if (this.sleepTimer) clearTimeout(this.sleepTimer); this.sleepTimer = undefined; in dispose() (and consider unref() at arm time).

Fixed as part of #194 (durable sleep/self-wake intent): dispose() now clears sleepTimer alongside the debounce and self-wake timers, and at 29341f7 both sleep and self-wake timers are unref()'d at arm time per your note, so a disposed gate no longer keeps the process alive or fires wakeFromSleep after disposal. If you'd rather have the two-line fix land separately ahead of #194, say so and I'll split it out.

Update: at e815e8c in #194 the unref() is reverted — Greptile pointed out it lets a standalone process exit before a promised wake fires. dispose() still clears sleepTimer and the self-wake timers, which addresses this issue's actual complaint (timer surviving disposal); a test asserts no live timer after dispose().
