Looks good. Relying on the test quite a bit for the logic not changing but went through it slowly and I think this is a much cleaner and manage code base.
Just a few questions but otherwise I"m good with it.

FWIW, this is also already in nornir-nautobot as a dispatcher function. I understand this is step 1 of this revamp, but keeping here for awareness for future.

Yes — I needed to simplify it initially so that I could more easily migrate to nornir-nautobot.

Yes, that's incorrect here.

I'm confused by this, mind explaining this a bit more?

Assuming the explaination from the previous comment, maybe we should move this somehow into constants.py

Summary
This PR is
Stage 1refactor before moving components out of onboarding app to nornir-nautobot.PR refactors the
netmiko_send_commandsfunction to remove duplicated logic, improve readability, and make command filtering more maintainable — without changing any behavior..Key Improvements
✅ Removed redundant loops and conditions
Consolidated repeated logic for handling commands as lists or dicts.
✅ Centralized skip logic
Introduced a single
command_exclusionsmapping instead of multiple scattered if not sync_* checks.✅ Decoupled jobs from automation runner
Removed job and job inputs dependency in lower level methods, separating them from actual user input
✅ Improved readability
Clearer handling of the "pre_processor" section and command collection flow.
✅ Behavior preserved
All original skip rules, deduplication behavior, and flag-based filters remain identical.
✅ Safer and cleaner
Uses get("commands", []) and .extend() for simpler and more resilient logic.
