The SDK parses and copies the complete transcript while forking a Claude
conversation. Running that work in the daemon's event loop blocks all
connected clients, even though only one conversation is being rewound.
Run the fork in a worker, stream transcript records, and append in bounded
chunks. Preserve the SDK's fork content, transcript location, and error
fields. Share the existing compiler worker loader and verify that the
installed daemon closure contains and starts the rewind worker.
Retain Dominic Anaeto's implementation and regressions from #8444, rebased
onto main to include the correction for the moved worktrees documentation
page in the website test.
Fixes#8209
