[Bug] Remote control session truncates plan output and fails to notify mobile client of required user input

Bug Description

1. Start a planning session on host machine
2. Initiate /remote-control during planning
3. Connect with Claude Mobile App
4. Host machine finishes planning and presents the results with the different options (Accept + allow edit etc) to the host machine session

Expected result:
A Notification indicating that claude needs user input.
The full plan presented on mobile, with the option to Accept, make edits etc. As with a regular claude session

Actual result:
Claude mobile app receives a small portion of the plan, and the Claude mobile terminal/chat just shows the loading icon on bottom of the cut-off plan. Unable to prompt any further.
There is also no notification from the mobile app about needing any input / accepting the plan
