colmena repl fails when used with direct flake evaluation. #287
Description
Hi! I am giving Colmena a try. colmena repl doesn't appear to work with direct flake evaluation.
With an ~empty colmenaHive definition in my flake.nix:
colmenaHive = colmena.lib.makeHive {};(I had more going, but I kept removing parts until I was satisfied the error wasn't related!)
colmena repl results in:
$ ../colmena/target/debug/colmena repl
warning: Git tree '/Users/kivikakk/g/vyxos' is dirty
[INFO ] Using flake: git+file:///Users/kivikakk/g/vyxos

Nix 2.24.12

I'm using my own build of df694ee to help me debug, but there's no modifications in this invocation.
I've dumped the Command executed by colmena repl:
Command { std: "nix" "repl" "--experimental-features" "nix-command flakes" "--file" "/var/folders/92/4t85zvr910d4qtnfnv06qn740000gn/T/colmena-repl-m2UqVE.nix", kill_on_drop: false }
And the content of the generated file:
with builtins; hive: assert (hive.__schema == "v0.5" || throw ''
The colmenaHive output (schema ${hive.__schema}) isn't compatible with this version of Colmena.
Hint: Use the same version of Colmena as in the Flake input.
''); hive.introspect (x: x)There's no reference to the flake in cwd here; I assume that's because FLAKE_APPLY_SNIPPET (which is the exact content of the file written out, above) is intended to be evaluated in the context of a flake in an invocation like nix eval .#colmenaHive --apply [EXPR].
Anyway, I guess all this isn't super necessary, since nix repl . and accessing colmenaHive.nodes directly seems to work! I should've tried that first, maybe. :)
