fix(devices): skip Apple device discovery on non-Mac hosts

[tris203]

Note

GPT-6 responding on behalf of @tris203

What Changed

Start the device hub with --platform android on Linux and Windows, for both local and SSH hosts. Mac hosts retain iOS and Android discovery, including when accessed from a Linux client.

Why

Opening device support on Linux currently shows an [apple-utils] error because the hub attempts xcrun simctl list devices --json. Filtering discovery on the machine running the hub prevents this unsupported probe while preserving Apple functionality and useful errors on Macs.

Validation

• 13 focused tests passed across LocalDeviceHost.test.ts and sshDeviceScript.test.ts.
• Targeted lint and server typecheck passed.
• Dev server started for maintainer testing.

Summary by CodeRabbit

Bug Fixes

• Device hub startup now selects the Android platform automatically on Linux and Windows.
• macOS continues using its default platform selection.
• Remote device hub launches now apply the same platform selection consistently across supported desktop platforms, improving reliability when connecting to Android devices from different operating systems.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — The production launch behavior for both local and SSH device hubs now filters non-macOS discovery to Android by default, changing the devices and discovery errors users see, while macOS remains unchanged. Focused tests cover the new platform-specific argument selection.

Notes:

• No code objects were reviewed. Approvability was decided on eligibility alone.

📝 Walkthrough

Walkthrough

The change centralizes hub arguments and adds Android platform selection for non-macOS hosts. SSH hub launches use the same behavior. Tests cover Linux, Windows, and macOS.

Changes

Hub platform selection

Layer / File(s)	Summary
Local hub argument construction apps/server/src/device/LocalDeviceHost.ts, apps/server/src/device/LocalDeviceHost.test.ts	hubArguments adds --platform android on Linux and Windows, preserves automatic selection on macOS, and is used by hub spawning. Tests cover all three platforms.
SSH hub argument propagation apps/server/src/device/sshDeviceScript.ts, apps/server/src/device/sshDeviceScript.test.ts	The SSH hub launch passes Android arguments on non-darwin hosts. Parameterized tests record and verify the generated hub arguments for Linux and macOS.

hubArgs assertions to control the simulated remote platform, exercising both
“darwin” and non-Darwin branches independently. Ensure the generated script
receives the same test-controlled platform value when launching the hub; assert
darwin omits --platform and non-Darwin passes exactly ["--platform", "android"].
