Base hash (check with +trouble):

0v1k.t6ush.on4eq.j9vik.j6r5j.2mnuh.18hij.53kr1.bftck.deos4.c35sb

Release notes:

- Add basic support for future terminal input types, to allow smooth
upgrade to terminal handling

- Add json reparsers for hex, jugs, dates, tanks, and recursive
reparsers

- Added +succ function to stdlib

- Various performance improvements:
- arvo:
- stop using +slay/+nuck when parsing part of a beam into a case
- prime compiler caches to be able to access the scry arm of vanes
faster
- eyre:
- switch from doing uncached dynamic %c conversions to doing cached
%f conversions
- graph-add-nodes thread and graph-push-hook:
- cast to update:store so that type specialization doesn't force us
to do unnecessary nest checks
- graph push hook / graph store:
- prime cache for all mark conversions
- cache scry results when applicable
- graph store:
- switch from using %b to scry a dais and run its noun:grab (vale)
and instead use a static %f cnversion from indexed-post ->
indexed-post for validation to avoid an unnecessary
