Workflow inputs (aka switching to strict syntax)

Template: Spring 2026
Linting (also nextflow lint): Spring 2026

This doesn't have required and optional because it's either on or off for using the new syntax parsers and there for the linting.

We plan to make the strict syntax enabled by default in 26.04, so that seems like a good time to start using new syntax in the template -- not just workflow inputs but also type annotations, etc

The main thing I want to stress for nf-core pipelines is that you'll want to separate "config" params from "script" params

• "config" params (that are only used by other config settings) should be defined in the config params block and not in the script

• "script" params (that are used in the script) should be defined in the script params block and not in the config, expect perhaps by a profile (e.g. test) to override the default value in the script
