🟡 Race condition: pending loadFunc promise overwrites #workerLoad after draining sets it to 1

#workerLoad is set to 1 when the draining guard runs at agents/src/worker.ts:687, but a previously-dispatched loadFunc call (which takes ~2.5s via cpuPercent at agents/src/cpu.ts:30-49) can resolve after draining starts and overwrite it at line 710 with a lower value.

Timeline: (1) interval fires, #draining is false, calls loadFunc() → returns a promise that takes ~2.5s; (2) drain() is called, sets #draining = true; (3) next interval fires, sets #workerLoad = 1; (4) the .then() from step 1 runs and sets #workerLoad = currentLoad (potentially < 1). The /worker HTTP endpoint then reports an incorrect load for up to 2.5s while the worker is draining.

Suggested change

	this.#workerLoad = currentLoad;
	if (this.#draining) return;
	this.#workerLoad = currentLoad;
