Brooklyn Nicholson 0d353ca6a8 fix(tui): bound retained state against idle OOM ... Guards four unbounded growth paths reachable at idle — the shape matches reports of the TUI hitting V8's 2GB heap limit after ~1m of idle with 0 tokens used (Mark-Compact freed ~6MB of 2045MB → pure retention). - `GatewayClient.logs` + `gateway.stderr` events: 200-line cap is bytes- uncapped; a chatty Python child emitting multi-MB lines (traceback, dumped config, unsplit JSON) retains everything. Truncate at 4KB/line. - `GatewayClient.bufferedEvents`: unbounded until `drain()` fires. Cap at 2000 so a pre-mount event storm can't pin memory indefinitely. - `useMainApp` gateway `exit` handler: didn't reset `turnController`, so a mid-stream crash left `bufRef`/`reasoningText` alive forever. - `pasteSnips` count-capped (32) but byte-uncapped. Add a 4MB total cap and clear snips in `clearIn` so submitted pastes don't linger. - `StylePool.transitionCache`: uncapped `Map<number,string>`. Full-clear at 32k entries (mirrors `charCache` pattern).		2026-04-19 18:43:40 -07:00
