// "Spawn similar" (#28): the seed a cloned session hands to a draft pane.
// Pure — the caller owns opening the pane.

/** Clone a session into draft values: same project, same command, same
 *  worktree decision, fresh name.
 *
 *  A worktree session seeds its *base repository*, not the checkout the daemon
 *  made for it: "similar" is another session of that project, and the daemon
 *  never adopts an existing worktree (docs/WORKTREES.md), so seeding the
 *  checkout would ask it to build a worktree out of a worktree. The picker
 *  then lands on that repository's box with "+ new" active.
 *
 *  `cwdRawVisible: false` keeps the two-step project picker on screen with the
 *  cloned project selected, instead of dropping the path into the free-text
 *  escape hatch.
 *
 *  The name is left out on purpose: a clone is a new session and takes its own
 *  generated handle. */
