Description

This PR removes all dependencies and dead code for Cobra, and removes Viper, as such slightly refactors config
Replaced YAML handling to goccy/go-yaml as I realised that the ghodss/yaml package was abandoned

Changes

• Removed dead code, hence a lot of deletions (remnants from removing Cobra)
• Removed dependencies on Cobra where relevant
• Removed dependencies on Viper (slight refactor to config and surrounding tests)
• Moved from ghodss/yaml to goccy/go-yaml as it's actively developed
• Ran go mod tidy to clean up imports and indirects
• Updated output flag across the board to enum to json, yaml, text and fixed hardcoded values for default

Testing

• [ X ] Tests have run locally (with go test ./...)
• [ X ] Code is formatted (with go fmt ./...)

Took a lot of pleasure removing everything, no AI stealing my joy.
