The author of Kona has written kerf which I believe is intended for this same space. I’ve never used it though. https://github.com/kevinlawler/kerf1

Dyalog APL Keyboard Layouts
Should you wish to type them on a normal keyboard:
https://abrudz.github.io/lb/apl has a browser bookmarklet which adds an APL language bar to the top of any web page so you can type in any input box with backtick prefixes.
https://github.com/abrudz/Kbd has a Windows Input Method Editor (IME) that adds system-wide RightAlt+letter combos.

Ngn/k (free K implementation)
This might have been true a couple of years ago but it is totally untrue now.
I'm not sure why you couldn't use the student version of Dyalog? Sounds like it would have been fine. There are also many more FOSS implementations of array languages now, such as ngn/k and April. https://github.com/phantomics/april
'only available for Linux' - not true https://github.com/abrudz/Kbd/ and others (also different input modes like `w for ⍵)
'no community support' - on the contrary there is a big and helpful APL community https://aplwiki.com/wiki/Chat_rooms_and_forums that is (imo) more useful than stackoverflow
'Dynamic scoping...' - Dyalog's (and other APL's) dfns have lexical scope.
'The language is extremely terse' - is this meant to be a bad thing?
'The code tends to be very hacky' - maybe if you write bad code or try and write C in APL (it won't work)
- Use TAB entry style in Dyalog for Mac?
