Miguel PalhasandClaude Opus 5 4bb732d9b9 perf(maestro): render terminals via WebGL
xterm's DOM renderer builds a node per cell, which is CPU-bound — the
wrong bottleneck on a phone, where an agent dumping output stutters
visibly on a Pixel 7 despite plenty of GPU headroom.

A WebGL context is scarce and revocable, so it follows the mounted view
rather than the connection: acquired in onMount, released in onUnmount.
ConnectionPool keeps MAX_PARKED connections alive behind the visible
ones, which would otherwise exceed the browser's context cap (~16 on
desktop Chrome, fewer on Android) and bring a parked terminal back
blank. Context loss falls back to the DOM renderer and retries against a
shared two-loss budget; a device that keeps dropping contexts stops
being asked. A device pixel ratio change rebuilds the glyph atlas, which
is otherwise left blurry.
