Consider: add multiplatform build instructions to `./readme.md`

[NiloCK]

Bubbletea is a nice toolkit for building tuis. One major point in Go's favour in this domain is that its built executables contain the language run-time: ie, can be run on any machine without installing language dependencies.

BUT, Bubbletea's documentation doesn't provide much in the way of smooth onramps to this feature. Devs building small side projects which might be of interest to other persons don't have time/energy/expertise to reproduce, for example, the contents of your own release script. Instead, these devs commonly provide the installation instruction go install github/somedev/someproject, which is intelligible only to go devs and not the broadest possible community of end users for these tui applications.

Suggestion: include in the readme a brief section with minimal instructions for either:

• a script which outputs executables for each major OS
• a github action which produces similar on version tags

Overall goal is to make it very easy for hobby devs to replace their go install ... installation instruction line with pointers like somedev/someproject/releases/latest, and a brief description of what users of each environment should look for.

edit: this section would fit nicely between the existing headings Debugging and Libraries we use with Bubble Tea. It could be called Building & Releasing or some such.
