Refactored internal code

Added trigger batching and published the component as an npm package:

• Added opt-in batching to the New or Modified Files trigger, dispatching each changed file individually or in configured batches; enabling it changes the shape a downstream step receives
• Published the component as an npm package, so code-native integrations can install it and call its actions, triggers and data sources from code with TypeScript types

Added Custom KEX Algorithms connection input to allow specifying custom key exchange algorithms

Updated spectral version

• Added New or Modified Files polling trigger that detects new and modified files in a directory on a configured schedule
