Replace the Windows tasklist shell-out in isProcessAlive with process.kill(pid, 0), unifying all platforms on the POSIX idiom. Node maps signal-0 to an OpenProcess existence check on Windows — and the Windows daemon runs under Node (dist/server-node.mjs + bun-polyfill, the documented oven-sh/bun#4253 fallback) — so the probe is portable. Why the shell-out had to go, beyond the cosmetic conhost flash the watchdog blinked into the foreground every 60s (#1952): a Bun.spawnSync that hits its timeout still RETURNS with partial stdout, so the `.includes()` PID match answered "dead" for LIVE processes under load — the false-negative half of the #2414/#2295 leak chain. Signal 0 spawns nothing, cannot time out, and is ~5 orders of magnitude faster (measurements in #2414). EPERM still reports alive (process exists, we just can't signal it). Layered on the post-#2414-absorb shape: test 3 in process-liveness-windows.test.ts now asserts the probe is subprocess-free on ANY platform (win32 exemption dropped), test 4's static tripwire loses its error-handling.ts exemption (a `tasklist … PID eq` existence probe anywhere in src/ now fails CI), and windows-spawn-hide.test.ts drops its tasklist-in-error-handling needle (nothing spawns, which is stronger than hiding the window). Tests: process-liveness-windows + windows-spawn-hide + error-handling — 17 pass, 0 fail. Fixes #1952. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
