Android trim callbacks are best-effort — LMK can kill without ever
delivering one — yet the RSS watchdog only ran on desktop with a fixed
1.5GB bar no 2GB TV box ever reaches before dying. The watchdog now
runs on Android with a threshold scaled to device RAM, an eviction
floor and cooldown against refetch churn, and a lower backgrounded bar
since a paused app is LMK's first candidate.
The logs-screen header and startup line now record the renderer, the
effects tier with its raw hardware signals, and the boot RSS, so
uploaded reports answer whether the reduced tier engaged.
