feat(init): add --yes flag to skip confirmation prompts

Add -y/--yes flag to the init command that skips interactive confirmation
prompts when configuring PATH. This allows non-interactive usage in CI
environments where integration tests call 'dtvem init --yes'.

- Add initYes flag variable and register with cobra
- Update AddToPath signature to accept skipConfirmation parameter
- Skip prompts on Unix when flag is set (shell config modification)
- Skip prompts on Windows when flag is set (elevation request)

Fixes #132
