feat(task): add golangci-lint tasks and fix Windows checks

Introduces new tasks for running `golangci-lint`, a powerful and fast Go linter. This includes `lint:golangci` for checking the codebase and `lint:golangci:fix` for automatically applying fixes.

Additionally, this commit corrects the command used for checking the existence of executables on Windows. The change from `where` to `where.exe` ensures better cross-platform compatibility and reliability within the Taskfile.
