feat(current): add --yes flag to skip install prompts

Add --yes/-y and --no-install/-n flags to the current command:
- --yes: automatically install missing versions without prompting
- --no-install: skip install prompts entirely (for CI environments)

Update integration tests to use --no-install flag to prevent
hanging on stdin in CI environments.

Fixes #136
