To pave the way for adding a new error type for builtins in this crate,
move DerivationError to a new builtins::errors module.

Assigning copyright to the TVL community (whatever that is), and
adding AGPL-3.0-or-later license.
I also cleaned up some of the stuff on the landing page.

Move the the `fixed:out:[r:]{}:` generation to a helper function,
use matches! for more clarity.

nixery.dev uses the vnd.docker.container.image.v1 format, which is
recognized by the OCI [1] and originally defined by Docker [2]. The
config field in this image format, which this commit is about, is
even portable between the Docker and OCI formats (the Docker Golang
library embeds the OCI definition [3]).
The attribute names in what's called ImageConfig in [3] are specified as
PascalCase, which effectively means that the names Env and Cmd used by
nixery need to be capitalized. The lowercase variant is not causing a
lot of issues because most container tooling is written in Golang, which
allows case-insensitive matches when deserializing JSON. Languages that
parse strictly either miss the configuration values, or fail due to
unknown attributes. This commit capitalizes Cmd and Env to accomodate
strict parsers.

Previously, Nix strings were represented as a Box (within Value)
pointing to a tuple of an optional context, and another Box pointing to
the actual string allocation itself. This is pretty inefficient, both in
terms of memory usage (we use 48 whole bytes for a None context!) and in
terms of the extra indirection required to get at the actual data. It
was necessary, however, because with native Rust DSTs if we had
something like `struct NixString(Option<NixContext>, BStr)` we could
only pass around *fat* pointers to that value (with the length in the
pointer) and that'd make Value need to be bigger (which is a waste of
both memory and cache space, since that memory would be unused for all
other Values).
Instead, this commit implements *manual* allocation of a packed string
representation, with the length *in the allocation* as a field past the
context. This requires a big old pile of unsafe Rust, but the payoff is
clear:
hello outpath time: [882.18 ms 897.16 ms 911.23 ms]
change: [-15.143% -13.819% -12.500%] (p = 0.00 < 0.05)
Performance has improved.
Fortunately this change can be localized entirely within
value/string.rs, since we were abstracting things out nicely.

As far as I can tell we can handle files and directories using the same
cp(1) invocation, so we no longer need to potentially IfD derivations in
the tree to figure out whether they are files or directories.

This reverts commit d9565a4d0af3bffd735a77aa6f1fd0ec0e03b14a.
Reason for revert: this was intentional - putting Rc::clone instead of
.clone is a common Rust idiom, and makes it explicit that we're cloning
a shared reference, not an underlying resource

With our values using bstr now, we're not restricted to only reading
files that contain valid UTF-8.
Update our `read_to_string` function to `read_to_end`
(named like `std::io::Read::read_to_end`), and have it return a Vec<u8>.
