Neil 15adbd9d18 fix(agent-hooks): guard every Windows missing-target fallback before it reads stdin (#19415) ...

A Windows hook whose target file is missing fell back to reading stdin and throwing it away. That read never returns when the caller abandons the pipe, which is what happens outside an Orca pane — one stuck process and a visible console per hook event (#11549).

The rule 'check the Orca env before you own stdin' existed once in cmd syntax and was retyped by hand elsewhere, so the PowerShell and Git Bash launchers never got it. Derive all three dialects from one list of vars and apply them wherever a missing target makes the caller the stdin owner.

- wrapWindowsHookCommand and the runtime-home PowerShell branch guard before ReadToEnd, and emit the fallback answer before the guard so a gate event outside a pane is not answered with silence.
- The runtime-home Git Bash fallback picks its rule by platform: POSIX keeps capture-first (#8110), Windows answers, guards, then drains.
- The Antigravity wrapper disables delayed expansion like its core; with a '!' in the hooks path it was missing the core on every event (#9358/#9941).

Tests drive the wrapper through the production 'cmd /d /c' chain under both delayed-expansion states, and the cross-agent ratchet covers the launchers with an abandoned pipe rather than requiring the unguarded drain.
