refactor: doc improvements (again)

[TorchedSammy]

HEY

the docs on hilbish are kinda iffy, so here is part 2 of adding more to the documentation (whether web generated or doc command)

and maybe even the emmy lua generated docs closes #254

doc showcase related:

• Make functions collapsed?
• [x] Table of functions (how would this be rendered in doc command?)
  • [x] How to render properly in doc command

the following need to be written for all functions:

• [x] Parameters
• [x] Examples

rewrite descriptions on:

• [x] Modules (Introduction)

  • [x] bait
  • [x] commander
  • [x] fs
  • [x] hilbish

• [x] Functions

• [x] Signals

• [x] Generated docs for lua written modules (nature)

• [x] Opts

---

• [x] I have reviewed CONTRIBUTING.md.
• [x] My commits and title use the Conventional Commit format.

• [x] I have documented changes and additions in the CHANGELOG.md.
