fix: decision extractor uses extract worktree + PR flow

Was writing directly to main worktree where daemon race condition wiped
files. Now: syncs extract worktree to main, creates branch, writes
records, commits, pushes, opens Forgejo PR. Same pattern as batch-extract.

Also checks both main and extract worktrees for existing records.
