Problem

When CI lint fails, the output shows the error but gives no hint how to fix it.
Users see this and have to figure out the fix command themselves:

Error: [lint:super-linter] Errors found in YAML_PRETTIER
Error: [lint:super-linter] Super-linter detected linting errors

Suggested approach

When a lint task detects failures, print a hint:

💡 Try 'mise run fix' to auto-fix lint issues, then re-run 'mise run lint' to verify.

This should apply to all flint lint tasks, not just super-linter — any task that
fails should suggest the fix command.

Acceptance criteria

• Lint failure output includes a hint pointing to mise run fix + mise run lint
• Hint makes clear that fix is best-effort (try + verify)
