Tomatick memory usage hit 6.13 GB, macOS flagged system-wide memory pressure

[MichalAFerber]

macOS's memory-pressure notification fired tonight ("You're running out of memory and your Mac may become noticeably slower"), naming Tomatick specifically at 6.13 GB.

Worth checking whether this is a leak that grows over a long-running session (menu bar apps that never quit are the usual suspect) — and whether the Go rewrite here reproduces it or already avoids it.

Fixed in v2.0.1 (#21), which is installed on mac-mini-desktop. Memory stayed flat for a full hour with a timer running.

Setup: PID 20164, launched 22:24 EDT. A 63-minute "Wash clothes" timer ran from 22:40:48 to 23:44:01 EDT (history.db rows 67 and 68). This covers the per-tick title churn that #16 never measured.

devops series (footprint -p, sampled over SSH from pve-claude, EDT):

Time	Footprint	RSS (KB)
22:24	75 MB	130,128	launch
22:29–22:39	50 MB	98,800 → 73,088	idle
22:44	119 MB	85,968	timer started 22:40:48
22:49–23:24	117 MB (all 8)	88,048 → 50,960	timer
23:29–23:44	117–118 MB	53,392 → 58,560	timer; completed 23:44:01

Over 60 minutes with the timer running, footprint went from 119 to 118 MB. Before the fix, 2.0.0 grew by 100–400 MB an hour. The one-time +67 MB step at the timer start is a plateau, not a slope.

Kim's independent series: local ps -o rss on the Mac, 02:44–03:24Z with the timer running. RSS went 74,416 → 50,480 KB and never rose.

Rollback: the old app is kept at ~/Applications/_rollback/Tomatick-2.0.0.app.
