jade 748d8310fa Fix the pages in the manual for Lix
This doesn't comprehensively fix everything outdated in the manual, or
make the manual greatly better, but it does note down where at least
jade noticed it was wrong, and it does fix all the instances of
referencing Nix to conform to the style guide to the best of our
ability.

A lot of things have been commented out for being wrong, and there are
three types of FIXME introduced:

- FIXME(Lix): generically Lix needs to fix it
- FIXME(Qyriad): re lix-project/lix#215
- FIXME(meson): docs got outdated by meson changes and need rewriting

I did fix a bunch of it that I could, but there could certainly be
mistakes and this is definitely just an incremental improvement.

Fixes: lix-project/lix#266

synopsis: The `--debugger` will start more reliably in `let` expressions and function calls
prs: 9917
issues: 6649

Previously, if you attempted to evaluate this file with the debugger:
```nix
let
a = builtins.trace "before inner break" (
builtins.break "hello"
);
b = builtins.trace "before outer break" (
builtins.break a
);
in
b
```
Lix would correctly enter the debugger at `builtins.break a`, but if you asked
it to `:continue`, it would skip over the `builtins.break "hello"` expression
entirely.
Now, Lix will correctly enter the debugger at both breakpoints.
