emrg: bump v0.2.16 — Windows cmd-window storm hotfix (rant 2026-08-09T13:16:36)

[argszero]

Summary

v0.2.16 hotfix release — carries the emergency Windows v0.2.15 regression fix (rant 2026-08-09T13:16:36: host observed continuous cmd-window popups that forced an OS restart, plus daemon startup failure leaving GUI/scheduler unable to connect).

Per host authorization (rants #16/#18: release without waiting for real-machine verification), this bump proceeds to Build Release on merge.

Version bump (7 files, 8 lines — same pattern as v0.2.15 #591)

• emrg/__init__.py, pyproject.toml, uv.lock: 0.2.15 → 0.2.16
• emrg/gui/package.json, emrg/gui/package-lock.json: 0.2.15 → 0.2.16
• packaging/build-runtime.sh, packaging/make-installer.sh: fallback version → 0.2.16

What's in this release (already merged to master)

• emrg: fix Windows cmd-window storm + daemon spawn throttle (v0.2.15 regression hotfix) #592 — Windows cmd-window storm fix: emrg/_win.py win32_no_window_kwargs() (CREATE_NO_WINDOW) splatted into all 34 subprocess call sites; GUI spawn throttle (3/lifecycle) + reconnect backoff (1s→…→60s); scheduler connect-failure exponential backoff; real emrgd.log tail in spawn errors.
• emrg: port-file self-heal + G43 PID guard — kill the zombie-daemon state #593 — Zombie-state root cause: daemon _port_keepalive_loop (re-asserts emrgd.port every 60s) + GUI _daemonProcessAlive() G43 PID guard (never delete a live daemon's port file).
• emrg: TUI daemon spawn throttle — complete the anti-storm fix #594 — TUI daemon spawn throttle (_MAX_SPAWN_ATTEMPTS=3 + reset on successful connect) + one-time throttle hint in _reconnect.
• emrg: evolution_prompt quick-ref — add #592/#593/#594 anti-storm fix entries #595 — evolution_prompt quick-ref entries.

Verification

• uv run pytest tests/: 652 passed
• GUI: 101 passed
• macOS/Linux unaffected (win32 branch is an empty-dict no-op)
• Host will verify on Windows (acceptance: ① zero cmd popups on GUI/TUI launch ② daemon starts / real error shown)
