What's Wrong?

Stopping one tool call in a parallel batch should cancel the remaining in-flight calls from the same turn.

Expected: All remaining edits in that batch are cancelled
Actual: Only the stopped edit halts; the other parallel edits continue executing
Impact: User intent to stop the operation is partially ignored, leaving files in a partially-modified state

What Should Happen?

all in-flight edits should be stopped
