With this, we can disambiguate the following `mg run` invocations:
```shell
$ mg run :foo # run the virtual target, foo, with no args
$ mg run -- :foo # run the empty target and pass the arg, :foo, to it
```

Something I missed last time reading through the process documentation
is that you can use a combination of `process` and `process-wait` to
determine the exit status of a child process *and* read from its
standard output. With `process*` we could even capture stderr, but we
probably want it mounted to the parent process' stderr anyways.

`mg repl` is essentially a shortcut for nix repl $(mg path //) which
comes up often enough for me. Launching a repl only really makes sense
in the repository root with how readTree works at the moment, so I think
this is a convenient addition.

in some cases, users might want to pass through flags for
nix-build (such as `-j`).
magrathea now accepts these as arguments to `mg build`, as long as
they are separated by `--`.
the arguments passed to `mg build` are parsed into a proper record,
which enables us to show users very clear error messages in case they
forget to use the `--` separator and keeping us future-compatible with
more potential arguments to magrathea itself.

This command builds the desired target and runs the executable produced
by it. If a directory is produced, it looks for a single (!) executable
in the bin directory. Dot files are ignored, so wrappers should
generally work. In the future we could provide a flag to select one of
multiple executables.
All arguments following the target are passed to the executable as is.
Examples:
mg run ops/mq_cli ls
mg run web/bubblegum:examples

I want to add a shortcut to build and run e.g. scripts that are depot
targets - for which it would be useful to not have stdout polluted by
magrathea itself.

All targets would have no trailing slash, so it was at least ugly that
// had one as the only legal target.

for global installations of magrathea, setting MG_ROOT can be a way to
switch quickly between different repositories (esp. in combination
with `cd (mg path)`).

this command prints the absolute directory for a given target. it can
be combined with shell aliases to add quick navigation commands.
unfortunately due to the nature of computers implementing something
like `mg cd` directly is not possible.

magrathea now does what it says on the tin - build and shell commands
can be used with the targets specified on the command line.
implementation notes:
* string representation of target has been changed to look like the
target spec format, this is now used in user-facing messages
* errors returned by the target parser make the program exit with
status 1
* normalisation could be done better (for example, maybe it makes
sense to always do it) but it's good enough for now

i'm not sure what happened here, but it works (yes, the fancy target
printing is completely unnecessary, but oh well):
#;152> (parse-target "foo")
#target(foo)
#;153> (parse-target "//foo")
#target(//foo)
#;154> (parse-target "//foo/bar")
#target(//foo/bar)
#;155> (parse-target "//foo/bar/")
#target(//foo/bar)
#;156> (parse-target "//foo/bar:baz")
#target(//foo/bar:baz)
#;157> (parse-target "//foo/bar/:baz")
#target(//foo/bar:baz)
#;158> (parse-target "//foo/bar:")
(error . "unexpected end of input while parsing virtual target")
#;159> (parse-target "//foo//")
(error . "unexpected root-anchor while parsing normal target")
the most notable thing is that trailing slashes are allowed in the
physical targets, since people may be autocompleting these on the
shell from folder names.

this is going to be a serious version of //tools/depot-build.
right now it doesn't support parsing any target specs yet, so only
shells and builds for the physical project of the current folder work.
