feat(maestro): one-word handles, quieter project boxes

Session handles are one word from a single 218-entry list — instruments,
forms, notation and theory, tempo and dynamics — replacing the
adjective-noun pair. A batch is shuffled, so it repeats only once the
wordlist runs out.

Project boxes show the parent directory instead of the full path: the
last segment is already the name line above it. The last command is gone
from the box, and picking a project no longer pre-selects it — the
directory and what runs in it are independent choices. Both changes land
in the TUI picker too, which mirrors the web form's rules.
