Refactor large files

[samayer12]

Describe what should be investigated or refactored

Some files in the codebase are rather large, (>400 LOC). Contributors can benefit from Easier Navigation, Better Modularity, Simplified Testing, and Improved Code Quality by refactoring large files when it makes sense to do so.

Links to any relevant code

Some files that are larger than 400 lines, and may be candidates for refactoring (as of v0.35.0):

• src/lib/watch-processor.test.ts
• src/lib/helpers.test.ts
• src/lib/assets/pods.test.ts
• src/templates/capabilities/hello-pepr.ts

Additional context

Generate the list yourself with the command: find src journey scripts -type f -print0 | xargs -0 wc -l | awk '$1 > 400 {print $2}' | grep -v -e "node_modules" -e "total" -e "package-lock.json" from project root.

Add the hold label, this story fits in nicely with some other refactor work, we will look to prioritize this at the same time.
