While the feedback for human users is mostly the same, it does in fact
matter for the LSP since the quickfix will be different depending on
whether we look for a top-level identifier or if we look for a
constructor.
The typical case we see in the stdlib is the `VerificationKey` and
`Script` constructors for `Credential`, often being mixed with
their types counterparts in aiken/crypto!

1. A new option `show_json_schema` which, when enabled, will print the JSON schema of the command output if the target isn't an ANSI-capable terminal.
2. Some modifications to the help message and error handling for the new option `show_json_schema`.
This is now done to avoid flooding the help screen with an entire
JSON schema. Plus, it makes the schema more easily exportable as an
actual JSON schema.
Before this commit, we would require those target a specific handler,
whereas they are in fact global to the entire validator.
So now, we recover the behaviour from before where we default to the
only available validator when there's no ambiguity.
Note that this also solves the need for repeatedly applying parameters
to each handler of a parameterized validator. The command now
rightfully apply parameters to each corresponding handler.
It has somehow always annoyed me that we have --trace_level (with 'trace' first) and --filter_traces (with traces, plural and last). Given that these two options are almost always used together, the inconsistency is frustrating.
Constants are like tiny programs, so they are bound by the same rules
as validators and other programs. In fact, functions are slightly more
flexible in that they allow generic constant expressions like
`List<a>`.
Yet, there is no way to contain such generic structure that contain
inhabitants in a way that satisfies the type-checker. In the example
of `List<a>`, the only inhabitant of that type that we can construct
is the empty list. Anything else would require holding onto some
generic value.
In addition, we can't force literal values into generic annotation, as
something like:
```
const foo: List<a> = [1, 2, 3]
```
wouldn't type-check either since the right-side would unify to
`List<Int>`. And again, the only right-hand side that can type-check
is the empty list without any inhabitant.
The added restriction on generic function is necessary because while
we allow constants to return lambda, we cannot (easily) generate UPLC
that is generic in its argument. By the time we generate UPLC, the
underlying types have to be known.
Without that, the language server might trigger awkward warnings about
unused imports due to trace stripping. So it's better to compile/check
projects in the language server in the most expanded form.
