Remote Control disconnects during active use

Bug Description

Remote Control (/remote-control) disconnects frequently, even while actively using the session remotely. The local terminal session remains alive — only the remote control connection drops.

Environment

• Claude Code version: 2.1.76
• OS: macOS Darwin 23.6.0 (Sonoma)
• Mac sleep: disabled (always on)
• Terminal: stays open, session is alive
• Remote access via: Claude iOS app

Steps to Reproduce

1. Start Claude Code session in a project directory
2. Run /remote-control
3. Connect from Claude iOS app
4. Use the session actively (sending messages, running tools)
5. Connection drops unexpectedly during active use

Expected Behavior

Remote control should stay connected as long as the local session is alive and network is available.

Actual Behavior

Remote control disconnects even during active use. The local terminal session continues running — only the remote link drops. Requires re-running /remote-control to reconnect.
