Fix shuffle first song not being shuffled

update_shuffle_indices now shuffles all indices when position is 0
(no tracks have been played yet), so the first track played is random
instead of always being tracks[0]. Directory playback now uses
q.current() to pick the first track, resolving through shuffled indices
when shuffle is active.

Also pins notify-rust version in Cargo.toml and removes PLAN.md
(superseded by TODO.md).
