🖥️ Desktop Sidecar No Longer Crashes

If you've been hitting random crashes in OpenCode Desktop — silent exits, missing notifications, grep/glob returning nothing — this release fixes the root cause. The Electron utility process that runs OMO doesn't expose Bun's shell helpers or its native streaming APIs. We rewrote every affected path to detect this at runtime and fall back to plain Node child_process + buffer-concat streaming. Affected surfaces:

• Native search (grep, glob) now reads subprocess output via a Node-safe stream collector instead of Response(stream).text() (#3919).
• OS notifications fall back to execFile with windowsHide: true when ctx.$ is absent (#4128, [#4061]).
• Ripgrep discovery on Windows uses where.exe with shell-free spawn — no more flashing console windows.
• Subprocess hardening propagated through binary-downloader, zip-extractor, and all 5 zip-entry-listing variants.

🔁 Background Agents Stop Echoing Themselves

Two long-standing reliability bugs are gone:

• Duplicate parent wakes — when a background subagent completed and the parent's promptAsync gate was still holding, the same wake could enqueue twice and start a second assistant stream. Resolved by semantic deduplication during the gate hold window (#4256, [#4019]).
• Cleanup listener retention — repeated transient errors during MCP startup or provider reconnects no longer kill the host. The uncaughtException listener stays installed across events, with a local re-entry guard that still prevents log explosions.

💬 No More Comment-Checker Deadloops

Editing a line that contained an existing comment used to trigger the comment-checker repeatedly even when the comment was unchanged. The checker now skips edits that don't introduce net-new comments and deduplicates warnings to once per 30s per session (#4292).

Pure bug-fix release. No new agents, no new tools, no config changes. If you're on v4.3.0, this is a drop-in upgrade.
