fix(mobile): keep store screenshots free of system banners and show dictation

[juliusmarminge]

Store screenshots captured by screenshots:mobile came out with a "Ready for Apple Intelligence" banner over the status bar, and the composer never showed the dictation button.

The banner is a CoreFollowUp item that generativeexperiencesd posts on an eligible iOS 26 simulator's first boot; followupd re-surfaces it on every later boot until someone dismisses it. The daemon skips the post when DateOfLastAppleIntelligenceReadinessCFU is already set in com.apple.generativeexperiences.corefollowup, so the runner now writes that marker and drops the CoreFollowUp store while the device is shut down, right before booting it. That prevents a fresh simulator from ever posting the banner and clears one an existing simulator already queued. Verified on both cases: the daemon logs should NOT post Readiness CFU and the items table stays empty across reboots.

The dictation button is gated on on-device transcription, which simulators never have. The composer now reports it available whenever the app was launched by the showcase runner with a scene, so captures show the real composer.

Note

Low Risk
Changes are limited to showcase automation and a showcase-only isAvailable override; normal app voice behavior on real devices is unchanged.

Overview
Store screenshot capture is adjusted so iOS simulators boot clean and the composer matches production chrome in showcase runs.

The mobile showcase runner now suppresses the “Ready for Apple Intelligence” system banner before each iOS boot: while the simulator is shut down it writes DateOfLastAppleIntelligenceReadinessCFU into com.apple.generativeexperiences.corefollowup and removes Library/CoreFollowUp, so generativeexperiencesd skips posting and any queued follow-up is cleared.

Voice input availability in useVoiceInputController now treats dictation as available when a native showcase scene is active (getNativeShowcaseScene() !== null), not only when on-device transcription exists—so simulator captures show the dictation button even though simulators lack local transcription.

Note

Fix iOS showcase screenshots to hide system banners and enable dictation in showcase scenes

• Updates useVoiceInputController to report voice input as available when a native showcase scene is active, even on devices without an on-device transcriber.
• Adds suppressIosSystemFollowUps in mobile-showcase.ts which sets the Apple Intelligence readiness preference and removes the CoreFollowUp store on a shut-down simulator before boot.
• Adds iosSimulatorDataPath helper to resolve a simulator's filesystem data path from its UDID, failing explicitly when not found.
• Inserts the follow-up suppression step into captureIos after shutdown and before boot so captured store screenshots are free of system banners.
• Risk: suppressIosSystemFollowUps deletes the simulator's CoreFollowUp store recursively; if the preferences directory path resolution in iosSimulatorDataPath returns the wrong path, it could operate on unintended simulator data.

Approvability

Verdict: Approved at 97985fb

Macroscope's review found this PR approvable — This is a focused mobile screenshot-capture adjustment: it cleans system follow-ups on the selected simulator and displays the existing dictation control only when showcase metadata is active. Normal transcription behavior and real-device app paths remain unchanged, with no schema, deployment, sensitive-area, default, or static-analysis changes.
