d0799a7aa4 fix(tazjin/nixos): delete firefox from machines
Quassel sometimes thinks it's a reasonable thing to do to start
firefox instead of my default browser. Why? I've got no clue.

But since I don't use Firefox anyways unless there's a special
situation going on, lets just delete it.

270b1084e8 feat(tvix/eval): use EvalIO::import_path when coercing paths
This "ties the knot" of importing files into a store when referring
to them through path literals, e.g. inside of strings.

I'm not yet sure if this interface is sufficient for
builtins.path (which we haven't implemented at all yet), but it's
enough to wire up eval & store initially.

In the default implementations nothing interesting happens in this
function at all.

947a56c4b6 feat(tvix/eval): builtins.storeDir
Returns the store directory through EvalIO::store_dir.

Note that this is _optional_ in Tvix, as an evaluation can occur in a
context where there simply is no store directory. In those contexts,
`builtins.storeDir` returns `null` in Tvix.

This would only happen in contexts like Tvixbolt (or completely
unrelated use-cases) in practice.

ec3e38c2d6 chore(tvix/eval): gate tvix_eval::StdIO behind the impure feature
This shouldn't be available if we've built a "pure" crate.

29790147b6 fix(tvix/cli): use tvix_eval::StdIO in CLI
... until we have a store-I/O layer, or something that intercepts the
store-related stuff appropriately.

0ef3c2fc2b refactor(tvix/eval): use EvalIO::read_to_string in impure builtins
With this change, the behaviour of reading a string from a file path
is controlled by the provided `EvalIO` structure.

This is a huge step towards abstracting away I/O behaviour correctly.

c3c4d752c9 feat(tvix/eval): add EvalIO to public crate API
This lets users set the `io_handle` field on an `Evaluation`, which is
then propagated to the VM.

25fc6b7c25 feat(tvix/eval): introduce initial EvalIO trait
This trait is going to be used to abstract filesystem interactions in
Tvix.

For now, it only contains a `read_to_string` method that closely
mirrors `std::fs::read_to_string`.

As a first step, to see how this works in practice, we will thread
through only this function to the various relevant parts.

Two implementations are provided in tvix-eval itself: A dummy
implementation (which just returns ErrorKind::NotImplemented for all
operations), and a std implementation which delegates to `std`
functions.

bf286a54bc refactor(tvix/eval): add a LightSpan type for lighter span tracking
This type carries the information required for calculating a
span (i.e. the chunk and offset), instead of the span itself. The span
is then only calculated in cases where it is required (when throwing
errors).

This reduces the eval time for
`builtins.length (builtins.attrNames (import <nixpkgs> {}))` by *one
third*!

The data structure in chunks that carries span information reduces
in-memory size by trading off the speed of retrieving span
information. This is because the span information is only actually
required when throwing errors (or emitting warnings).

However, somewhere along the way we grew a dependency on carrying span
information in thunks (for correctly reporting error chains). Hitting
the code paths for span retrieval was expensive, and carrying the
spans in a different way would still be less cache-efficient. This
change is the best tradeoff I could come up with.
