Subject: [PATCH 1/2] fix: add --no-sandbox to antigravity launch command

Electron apps crash in Docker without --no-sandbox and
--disable-dev-shm-usage, same as Chrome. VSCode handles this
internally; Antigravity does not.

Subject: [PATCH 2/2] fix: mount memory-backed emptyDir at /dev/shm for
 Electron apps

Instead of disabling shared memory usage, mount a proper tmpfs at
/dev/shm so Antigravity (and Chrome) have real shared memory available.
Removes --disable-dev-shm-usage; keeps --no-sandbox (separate issue).
