[BUG] iOS app crashes when fetching environment list if any remote-control server (kind: "bridge") is registered

What's Wrong?

The Claude iOS app crashes immediately when tapping the environment selector ("cloud" button) to choose where to run a session. The crash occurs whenever at least one claude remote-control server is registered — regardless of platform (macOS or Linux), working directory, path names, or capacity settings. Stopping all remote-control servers resolves the crash. The web app (claude.ai/code) handles the same environment list without issue.

What Should Happen?

The environment list should load and display all environments including kind: "bridge" (remote-control server) entries, just as the web app does

Error Messages/Logs

No error message is shown — the app crashes silently. The environments API response that triggers the crash looks like this:

  {
    "environments": [
      {
        "kind": "bridge",
        "environment_id": "env_01DnCKcXXX",
        "name": "XXX",
        "created_at": "2026-06-06T20:40:53.426078Z",
        "state": "active",
        "config": null,
        "bridge_info": {
          "max_sessions": 32,
          "machine_name": "XXX",
          "directory": "/XXX",
          "branch": "cf-webview-proxy",
          "git_repo_url": "https://xxx.git",
          "online": true,
          "spawn_mode": null
        }
      },
      {
        "kind": "anthropic_cloud",
        "environment_id": "env_014LUPUtzgHUjii2XXX",
        "name": "Default",
        "created_at": "2026-03-19T04:07:27.279781Z",
        "state": "active",
        "config": null,
        "bridge_info": null
      }
    ]
  }

When only kind: "anthropic_cloud" entries are present, the list loads without issue.

Steps to Reproduce

1. On any machine (macOS or Linux), run claude remote-control from a git repository directory
2. Confirm the environment is registered — it appears correctly in the web app at claude.ai/code
3. Open the Claude iOS app
4. Tap "New Chat" → tap the cloud/environment selector button at the top
5. App crashes immediately

Additional Information

• The web app (claude.ai/code) correctly displays and handles kind: "bridge" environments — this is iOS-specific
• Related issue #44805 describes a separate but potentially related problem where git_repo_url in bridge_info triggers an erroneous GitHub auth check — the crash here may stem from a similar mishandling of bridge_info fields
• The spawn_mode: null field in bridge_info is a possible null-handling crash candidate
• Isolation confirmed: Mac server, Pi server, directory with spaces, directory without spaces — all crash iOS if kind: "bridge" is present. Removing all bridge environments = no crash.
