Remove the concept of fragile reductions
...
They were a vestige of when Tree-sitter did sentential form-based
incremental parsing (as opposed to simply state matching). This was
elegant but not compatible with GLR as far as I could tell.

Account for epsilon external tokens when merging parse states
...
Do not merge a token T into a parse state S if S contains
external tokens that can be *followed* by tokens that could
be shadowed by T.
At this point, the only automated test for this logic is via
the bash grammar, in which the `]` token should not be merged
into states in which `_concat` is valid, because `_concat`
can be followed by a `_special_characters` token, and `]`
would shadow `_special_characters`.

Fix hole in logic for terminating tree balancing
...
It's important that the repetition nodes have a child count of 2,
because we assign to their second child. We could maybe generalize
this to allow balancing in the presence of 'extra' nodes like comments
and errors, but this might be complicated.
