fix(template): replace click.confirm with input() to avoid ^M on Linux terminals

click.confirm() doesn't strip \r — "y\r" doesn't match "y" and the prompt
loops or fails. Replace with raw input().strip().rstrip('\r').lower() which
handles both \n and \r\n line endings.

Also add --recreate-snapshot flag to skip the interactive prompt entirely
(useful for scripted re-provisioning).

Update snapshot_exists_skip/recreate tests to monkeypatch builtins.input
instead of using CliRunner input=.
