Split CI Workflows by Platform and Task, Improve Formatting and Linting Reliability (#108)

- Added CI badges to the README
- Added YAML linting to CI
- Added missing license headers and C header include guards
- Extended the pre-commit hooks to remove trailing whitespace, check licenses, format, and lint files
- Split CI into multiple workflow files: one per platform, one for lint & license, one for general Deeploy tests, one for infrastructure, and two for Docker flows, improving maintainability and status reporting
- Extended CI to check license in CMake and YAML files
- Removed all trailing whitespace
- Fix license CI check and prevent potential issues with `jq` installation
