2025 01 25 Project cleanup

[baalimago]

I've added three code-checkers and one vulnerability check to ensure that the code quality is high:

• Staticcheck is practically the successor to go lint, used to spot easy mistakes and homogenize the code to standardized idioms
• gofumpt is like go fmt but stricter. If any diff is detected when it's running, pipeline will fail. This ensures there are no formatting changes in the codebase
• go vet is a bit like staticcheck and ensures that there's no dangerous 'low hanging fruit'-errors
• go vuln tool which looks through the packages of the project and reports any vulnerabilities

These tools yielded a lot of errors, and some are still there even after this PR is merged.
My idea is to work on these bit by bit, not solve all in this PR since this neighboring PR fixes some, for example.

TL;DR changes:

• Added gofumpt, staticcheck, go vet and govulncheck into pipeline
• Formatted all files
• go mod tidy on all gomods
• Fumpted the go
• Cleaned up the existing pipeline so that it runs
