Patch Changes

• Antigravity run mode, plus opt-in entrance animations.

  Antigravity CLI backend (#207). Antigravity (agy) joins Claude Code, shell, OpenCode, Codex and Gemini as a sixth session backend, following the same pluggable-resolver pattern: utils/antigravity-cli-resolver.ts resolves the CLI and GET /api/antigravity/status reports availability and path. ANTIGRAVITY_* is added to the ALLOWED_ENV_PREFIXES allowlist so env overrides stay CLI-scoped rather than blanket-forwarded. Like the other external CLIs it requires tmux with no direct PTY fallback, because secrets are injected through socket-scoped tmux setenv and never on the spawn command line. The UI gains a Run-dropdown entry, an agent-type option, an ag tab badge and toolbar colours; runAntigravity() routes remote and docker cases through POST /api/quick-start and skips the local status probe for them.

  Entrance animations (opt-in, OFF by default). Optional animations for the four things that appear when work starts: session tabs, the terminal pane a session's CLI runs in, floating agent windows, and the connection lines tying a window back to its parent tab. Defaults are the legacy theme, so an untouched install behaves exactly as before and every hook short-circuits on its first line. Choose a look in App Settings > Appearance > Entrance Animations (per-device, stored in localStorage rather than the settings payload); ?animlab=1 opens a per-surface picker with a live preview that fakes tabs, a pane, a window and a line so styles can be compared without spawning sessions.

  Three implementation notes worth knowing if you touch this: tabs and connection lines are destroyed mid-animation on every re-render (_fullRenderSessionTabs() replaces the strip's innerHTML, _updateConnectionLinesImmediate() clears the SVG), so both are tracked by id and re-applied to the fresh element with a negative animation-delay that resumes rather than restarts them; terminal-pane styles animate transform, opacity and clip-path only, because xterm's FitAddon derives rows and columns from the untransformed layout box and animating width or height there would resize the PTY; and window styles that transform also move the rect their connection line aims at, which is why the beam style animates opacity and filter only.

  Also fixes an agent window spawning hidden (its agent belongs to a background tab): being display:none it never ran its animation, so animationend never fired and the entrance class plus its inline custom property stuck to the window permanently. Hidden windows now skip the entrance entirely.
