Fix cold-start overlay recursion that overflowed the main-thread stack when recording began while the ready overlay was still up; also remove temporary on-screen Flow DEBUG panels after the orange-mic investigation, and land the macOS overlay/catalog/layout polish plus related Flow recovery hardening.

// HostAppLauncher.swift

// OSGKeyboard · Keyboard Extension
|
||
//
|
||
// Opens the host app from the keyboard extension.
|
||
//
|
||
// Reality check (verified against iOS 18–26 behaviour):
|
||
// • The deprecated `openURL:` selector hack was disabled in iOS 18
|
||
// ("BUG IN CLIENT OF UIKIT … migrate to open(_:options:completionHandler:)").
|
||
// • Primary path: walk the responder chain to `UIApplication` and call the
|
||
// non-deprecated `open(_:options:completionHandler:)`. This requires Full
|
||
// Access and grows less reliable on newer iOS, so we report the *real*
|
||
// success from the completion handler instead of assuming it worked.
|
||
// • Fallback: `extensionContext.open`. Historically documented for Today
|
||
// widgets only (and it used to resolve `false` for keyboards), but it is
|
||
// the Apple-documented API for extensions to open URLs and ships in
|
||
// production keyboards on current iOS — worth trying before giving up.
|
||
// When both paths fail, callers degrade to on-keyboard guidance.
