[BUG] PyCharm IDE plugin: diff-accept no longer triggers automatic continuation (regression since recent update)

What's Wrong?

Until recently, accepting a diff in the PyCharm Claude Code plugin (clicking Apply in the diff view) would automatically signal Claude Code to continue — no further input was needed. After a recent update to Claude Code this stopped working. The PyCharm plugin itself has not been updated; only Claude Code was updated.

Claude Code waits indefinitely after a diff is accepted. The user must type a message (e.g. "ok", "go ahead") to trigger continuation.

What Should Happen?

Claude Code should automatically continue after the user accepts a diff in the PyCharm plugin, as it did in previous versions.

Error Messages/Logs

No error messages

Steps to Reproduce

1. Open a project in PyCharm with the Claude Code plugin installed.
2. Ask Claude to make a code change. Claude calls Edit and a diff appears in PyCharm.
3. Click Apply (accept the diff) in PyCharm.
4. Expected: Claude Code detects the acceptance and continues automatically.
5. Actual: Claude Code does not respond. A manual message must be sent to continue.
