refactor: extract wizard infrastructure into utils

[hanna-skryl]

create-cli will soon integrate create-eslint-config's wizard. Without a shared tree, each would buffer writes separately and we'd maintain two implementations. Sharing one gives us a single buffer and one canonical implementation.

The shared module uses create-eslint-config's implementation rather than create-cli's, because it already handles flush rollback, skips writes when content matches disk, and avoids re-recording identical writes, which create-cli was missing.

Additionally, this PR consolidates plugin binding inputs into a single object and extracts the yargs setup, fixing a latent bug where plugin-namespaced CLI flags silently no-opped instead of overriding their prompt defaults.
