✨ universal locks across environments

[juftin]

Closes #12

Summary

• This PR implements the use of the default lock file as a constraint file on a non-detached environment
  • This use of lock files as constraints files also requires that we disable the pip-compile-strip-extras feature as all lock files will need to be constraints compatible.
• This PR separates some key lockfile operations into a new class, lock.PipCompileLock. This will help to eventually integrate the header functionality into a CLI outside of a hatch plugin

See requirements-docs.txt as an example.

I see there are some missed assumptions about "default" stuff in Hatch.

https://hatch.pypa.io/1.7/config/environment/overview/#inheritance

Hatch environments have inheritance of all values. Any environment can choose to inherit from another environment. Multiple levels of inheritance are possible. The config for that is called template.

The environment named "default" has only these special things about it:

• It always exists.
• You don't need to spell out its name when using hatch run.
• Every environment has the default value of template = "default".

I can create a new environment named "shmefault" and never use "default".

And here's an example of 2-level-deep inheritance:

[envs.shmefault]
template = "shmefault"
dependencies = ["dep1"]

[envs.env2]
template = "shmefault"
extra-dependencies = ["dep2"]

[envs.env3]
template = "env2"

hatch env show env3 has dependencies dep1 dep2

Further:
It's not specifically the environment named "default" that gets the project itself as a dependency. Any environment directly controls whether it will have the project itself installed. So we can get this:

[envs.default]
skip-install = true
dependencies = ["dep1"]

[envs.env2]
skip-install = false
extra-dependencies = ["dep2"]

So here the "default" env will have only dep1, but the "env2" env will have the project itself installed and dep1 inherited and dep2

Separate comment: the config detached is only a shorthand for writing skip-install = true template = "{env_name}", so it is incorrect to check for it. Luckily it's easy to change, you just check for self.skip_install instead.

Good stuff!
