fix: Fix scoring of type and function declarations (#1290)
Previously, there was an edge case whereby types that depended on other
types that were not scored yet and functions that in turn depended on
these types could be assigned the same score. When this happened, we'd
sometimes incorrectly emit functions before the struct types they
depended on.

Since functions are always at the bottom of a type hierarchy (they
always depend on their members), there's a simple fix: we just add 1 to
ensure functions are emitted after type declarations in all possible
cases.

fix: fix repl function application evaluation (#1238)
The previous pattern matching changes introduced a subtle error in the
evaluator's handling of function applications, we used the same Resolver
for both lists and symbols, where previously we hadn't. Restoring the
old resolution selection and adding a new clause to capture forms like
((defn f [] 2)) restores the correct functioning in the repl.

Importantly, forms such as ((defn foo [x] x) 3), should only be resolved
when the defn form is the result of expanding a symbol.

Eventually, resolving defns to anonymous functions might simplify this
case.

fix: allow function arguments to shadow commands (#1217)
This fix is a close cousin of the one that allowed let bindings to
shadow global commands. We now allow function arguments to shadow
commands as well by using a local lookup preference for argument names,
making functions such as:

```
(defndynamic foo [car]
  (Symbol.prefix car 'foo)
```

work as anticipated. I've also removed unused code from `apply`.

fix: don't expand inner module macros on first pass; privacy (#1216)
* fix: don't expand inner module macros on first pass; privacy

This commit changes the behavior of expansions to avoid expanding module
expressions until we're actually processing the module in question.

Previously, the following form would be entirely expanded at the time of evaluating A:

```clojure
(defmodule A <- current environment

  (some-macro) <- expand

  (defmodule B
    (some-macro f) <- expand, current env is A, *NOT* B.
    so if this expands to
    (private f)
    (defn f ....)
    the f of the expansion is added to *A*, and we have a duplicate
    ghost binder.
  )

  (defn foo [] B.f) <- expand, B.f does not exist yet, any meta on the
  binding will be ignored, permitting privacy errors since expansion
  ignores undefined bindings, instead, we'll look this up at eval time,
  and not check privacy as doing so would cause problems for legitimate
  cases.
)
```

This meant that if the macro happened to have side-effects, e.g. calling
`meta-set!` we'd produce side-effects in the wrong environment, A,
resulting in duplicate bindings, missing bindings at evaluation time,
and other problems.

Now, we instead process the form as follows:

```clojure
(defmodule A <- current environment

  (some-macro) <- expand

  (defmodule B
    (some-macro f) <- wait
  )

  (defn foo [] B.f)
)

;; step 2
(defmodule A

  (foo-bar ) <- previously expanded macro

  (defmodule B <- current environment
    (some-macro f) <- expand
  )
  ....
)
```

In general, this prevents the generation of a bunch of unintentional and
incorrectly added bindings when calling `meta-set!` from various macros.

Additionally, privacy constraints are now carried across nested modules:

```
(defmodule A
  (defmodule B
    (private f)
    (defn f [] 0)
  )
  (defn g [] (B.f)) ;; Privacy error!
)
```

This change also fixed an issue whereby recursive functions with `sig`
annotations could trick the compiler. Again, this had to do with the
unintentionally added bindings stemming from expansion of nested module
expressions via meta-set.

Fixes #1213, Fixes #467

Fix: Allow shadows of global commands, allow recursion in let bindings. (#1214)
* fix: don't shadow local bindings with dynamics

This commit adds a new lookup preference to the evaluator, LookupLocal,
and uses it to lookup bindings in the scope of let forms. This fixes an
issue whereby our original bias toward dynamic bindings would prevent
users from shadowing dynamic bindings with local bindings of the same
name. Before the following code returned `command c`:

```
(defdynamic test-val (let [c (car (list 1 2 3))]
                        c))
```

It now returns `1`.

I also fixed a small issue with top-level (as in, without a
corresponding function environment) let forms (they'd cause a crash for
lack of an environment parent).

Fixes #659

* refactor: only prefer local lookups for shadows

The prior commit introduced a local lookup preference into the evaluator
in order allow for shadowing of global names in local scopes (like let
bindings). However, this introduced prohibitive performance costs,
especially for dynamic functions.

To mitigate this, we only perform local-biased lookups for a set of
known-shadows. Since we know the names of local bindings at form
evaluation time, we can restrict our local lookup bias to these paths
only. This greatly reduces the performance penalties initially incurred
by the change.

I've also refactored some of the lookup code for clarity.

* fix: support recursive let bindings

Previously, the bodies of anonymous functions bound to a let name did
not have access to their names, making recursion such as:

```
(let [f (fn [x] (if (= x 1) x (f (dec x))))] (f 10))
```

impossible. We now equip evaluation of let bindings with an additional
recursion environment making this possible. The example above will now
resolve to `1`.
