A medley of issues here:

1. Executing `treesit-explore-mode' on a buffer with no valid grammar
support causes the minor mode (and playground buffer) to stick around and "load" anyway.

2. Bailing out of the grammar prompt does not, in actual fact, stop explore mode from proceeding. Instead it creates an empty buffer and it still engages the minor mode.

3. Killing the playground buffer does not remove the explore mode buffer.

4. treesit-explore-mode is stored against a buffer during `desktop-save' (and subsequently read with) `desktop-read'. Thus broken buffers or files inherit the explore mode. This is especially pernicious due to #1, #2, and #3.
