v0.2.44 resolves multi‑minute hangs under parallel load and stops devices from wedging offline after sleep or WiFi loss.

Why it matters: Fixes tool‑call hangs that could stall operations for minutes; prevents device offline wedge caused by unbounded `joining` state, improving reliability of real‑time channels.

Summary

AI summary

Fixed multi‑minute hangs under parallel load, prevented devices from wedging offline after sleep/WiFi loss, and stopped write_file from silently clobbering files when the mode is omitted.

Full changelog

🐢 Multi-minute tool-call hangs under parallel load — fixed — under heavy parallel file I/O, tool calls (even in-memory ones like list_processes) could stall ~4 minutes then recover. Stats persistence is now non-blocking, the libuv threadpool is raised to 16, and stalled reads are cancelled via a flat 3-minute abortable timeout that fails before the client's opaque cutoff. #535
🔌 Remote: device no longer wedges offline after sleep/wifi loss — a half-open socket could park the realtime channel in joining forever, leaving the device offline until restart. Time-in-joining is now bounded, forcing a channel recreate instead of wedging. #528
🛡️ write_file won't silently clobber a file on a missing mode — an omitted mode used to default to rewrite and replace the whole file, so a dropped param on an intended append could destroy content. Writes to existing non-empty files now require an explicit append/rewrite. Creating new or empty files keeps the zero-friction default. #546
🖼️ More reliable file previews — the preview widget now renders every file type from its own read_file pull, with structuredContent returned as metadata-only on UI reads (no content duplication for the model). An 8s RPC bound and 10s watchdog replace a preview that could spin forever. #536
