refactor: refactor code and update linter config

- Add a new `.golangci.yml` configuration file with a list of enabled linters
- Exclude `lll` linter for lines starting with `//go:generate`
- Replace `strings.Replace` with `strings.ReplaceAll` in `plugin.go` for markdown escaping and error message sanitization
- Simplify time addition expressions in `plugin_test.go` by removing unnecessary `time.Duration` conversions
