chore: add golangci-lint tasks and force LF on Go files

Add VS Code tasks to run golangci-lint (with and without --fix) and mark
*.go as text eol=lf so Go sources check out with LF, avoiding spurious
CRLF lint failures on Windows. Also drop the now-redundant explicit
DockerInit.sh/DockerEntrypoint.sh entries already covered by *.sh.
