v1.2.0 — Sticky Toast + Keep-Alive

Fixed

• plugins/llm-statusline.toast.ts: toast is now sticky (duration=0 = never auto-dismisses). A keep-alive setInterval re-fires the toast every 4 min as a safety net, so the bar never disappears — even between model responses.
• Both plugins: version field was hardcoded to "opencode" (rendering 📟 vopencode). Now spawns opencode --version at init time.

Added

• LLM_STATUSLINE_TOAST_MS env var to override toast duration (default 0 = sticky).
• client.app.log calls for structured logging.
• Keep-alive timer (setInterval every 4 min).

Changed

• TOAST_MS defaults to 0 (sticky, never auto-dismiss).
