Include args in task cache file name hash

[bollwyvl]

Problem description

As of pixi 0.55.0 (and probably earlier), two "leaf" tasks may depends-on the
same "template" tasks in the same environment, inputs, and outputs, but with
different arg values. As only the environment name and file hashes seem to have an
impact, running the leaf tasks interleaved appears to always encounter a cache miss,
and the tasks always run.

Consider a template task that calls a linter/formatter tool like ruff, which
always considers the same python files.

dependencies.ruff = "*"

[tasks]
touch = """echo 'print("hello world")' > foo.py"""
fix.depends-on = [{task="_ruff", args=["1"]}]
lint.depends-on = ["_ruff"]
_ruff = {args = [{arg="fix", default=""}], inputs = ["*.py"], cmd = """
  ruff format {{ "--check" if not fix }} && ruff check {{ "--fix-only" if fix }}
"""}

[project]
name = "foo"
platforms = ["linux-64", "osx-arm64", "win-64"]
channels = ["conda-forge"]

Then:

pixi r touch
pixi r fix && pixi r lint  # expect to see run...
pixi r fix && pixi r lint  # ... expect to see a cache hit

No amount of doing this will cause the cache to "settle".

design ideas

I think it might be a matter of adding the task args to the hash file name.
Will try a PR.

Seems like #4676 is doing the thing.

Still burning coal updating #4676 to main...

This appears to have made the team for 0.56.0, thanks!
