Jinwoo-H 4dd1b16039 fix(mobile): start the terminal document per mount (ruling 20)
Round 1's blocking finding: ES module bodies run once per page, so the page's
second mount re-imported nothing and inherited the first mount's elements,
listeners and error reporter. Measured after a remount: zero .xterm nodes in
the live DOM, no selection overlay, nothing reaching onEngineError, and
onWebReady still firing.

Ruling 20: no emitted module does work as it is parsed. Every top-level effect
moved into an exported per-module start function — 86 statements across 14
modules, plus three parse-time captures whose declarations became typed lets.
The generator emits one call sequence in module order at the foot of the
document, so the native script still runs them once at parse; the page runs the
same sequence per mount and dispose undoes the three that outlive the host
element (tap-dispatch, webgl-recovery, host-notify).

installErrorReporter now hands back its own undo, so it stays five seams at six
document sites rather than growing a sixth.

M2: a failed document chunk was an unhandled rejection with no engine error.
It now goes down the document's own reporting path, so the overlay names the
cause instead of the 15s readiness watchdog. Pinned by refusing that chunk at
the wire in the render check.

L3: the seam count now reads five fields / six sites / three files everywhere.
L4: three unrelated web-overrides entries keep main's escaping.
