Adding support for CI hooks

A feature I would really like to have is being able to trigger CI on pushes to main (or on releases?)

Thinking out loud, but would it be possible to

• Identify some key lifecycle events. Maybe Pushed (to main) and Released?
• Identify some function name/signature to use as a convention (maybe ci : ShareEvent -> {IO, Exception} ())
• When events are triggered, if this function exists in the project, run the CI function?

Might need to figure out how unit tests fit into this as well (Maybe there should be another ciConfig function that returns a CIConfig with some data on how to handle this?). But even with just the above I could do something like

ci event = match event with
  Pushed (Branch "main") -> 
    deployStage
  Released -> 
    result = runIntegrationTests
    if result then deployProd else (throw ErrorThatBlocksRelease)
  _ -> ()

Would also be down to try to contribute for this but would need a lot of help ;)

The issue names no files, tests, or entry points. Start by reviewing the repository structure and existing CI or release integration, then clarify the lifecycle events, callback convention, configuration model, and unit-test behavior before implementation. Done means an agreed design and working support for the selected CI hooks.
