The working-directory picker was a flat list mixing repositories with
their worktrees, each row repeating the project name as an abbreviated
path. It is now two steps: a grid of project boxes carrying the full
unabbreviated path, then — only once a project is picked — that
repository's worktrees with "+ new" as the default.
"+ new" creates a worktree; picking an existing one runs in it and
leaves the create-worktree toggle off, since the daemon never adopts
(docs/WORKTREES.md). That is #91's rule, now an explicit choice rather
than an inference from which row was clicked.
Also fixes `.raw-wrap[hidden]`: `display: flex` outranked the UA sheet's
`[hidden]`, so the free-text cwd input showed even when hidden.
The interaction rules are listed in spawnForm.ts for the TUI mirror (#96)
to follow.
