Bundle Bun for headless Orca and profile persistence (#22635)

Bundle a pinned, verified Bun runtime for headless Orca so existing Node launch commands can hand off before opening a profile. Keep desktop execution on Electron.

Add the Bun SQLite adapter and terminal backend, bounded shutdown, process inspection and cross-platform artifact qualification. Keep future managed SSH deployment separate from current production launch paths.
