Separate CLI from runtime

[bentsherman]

This PR splits the nextflow module into two modules:

• nf-cli-v1: contains only the Launcher and CLI classes
• nextflow: contains everything (i.e. the "runtime")

Benefits:

• Improves build time, editing CLI code doesn't rebuild the entire project
• Removes some circular dependencies, making the code easier to read/understand
• Library consumers like platform or plugins can just depend on the runtime and not the CLI
• Makes it easier to implement a CLI v2 in the future

I separated the CLI bits in ConfigBuilder into a separate class ConfigCmdAdapter in order to keep the core config builder in the runtime. This also provides a nice separation of concerns.

Due to the nature of this PR, I will keep it updated via rebase instead of merge commits so that the changes are as clear as possible.

oh mamma mia 😆

Your k8s plugin inspired me 😄

[pditommaso]

I feared that 😆

Jokes aside, it might be good to do the actual code changes in a separate PR so that the nf-runtime part is as clean as possible

The nf-runtime refactor was just the easiest way to reveal the circular dependencies

I'll review post 25.04

Refactored so that the CLI code is in a new module nf-cli-v1. Made the PR considerably smaller

Note the following plugins depend explicitly on the CLI code because they add CLI commands:

• nf-console
• nf-k8s
• nf-tower
• nf-wave

Might be possible to remove this dependency by moving some interfaces into the core runtime, but not a big deal either way

[bentsherman]

I refactored the nf-lineage module to depend on nextflow and be required by nf-cli-v1. This removes the need for the LinCommand interface as the lineage command can simply use LinCommandImpl directly.

Couldn't quite do this for nf-k8s because the K8sDriverLauncher uses CmdRun, so that's a pretty hard dependency on the CLI v1. We could make nf-k8s a module instead of a plugin, but then it would be included at build-time instead of runtime.
