Discard selection history when file size changes

Pull request overview

Adds a content-length check to invalidate stored selection history when a file’s size changes (likely due to external edits), preventing restoring stale selections.

Changes:

• Persist a per-file content length alongside saved selection ranges and invalidate history when the length differs on restore.
• Extend the bridge LineColumnInfo payload to include contentLength (CodeMirror doc length).
• Update editor reset/restore flow to pass a length value (skipping the check for CR/CRLF-normalized content).
