feat(mirror): cluster picker for interactive one-shot mirror create

[toothbrush]

https://entire.io/gh/entireio/cli/trails/764

entire repo mirror create owner/repo on a terminal now offers the available clusters as a picker when [cluster-host] is omitted — pre-selecting your jurisdiction's default, and skipping the prompt when only one cluster exists (same shape as entire repo clone).

Non-interactive runs are unchanged: fixed default aws-us-east-2.entire.io, no network lookup, so scripts stay stable.

Restores the interactive half of what #1519 walked back, without reintroducing catalog guessing for scripts.

Note

Low Risk
CLI UX and cluster selection only; explicit cluster args and non-interactive defaults are preserved, with no auth or mirror API behavior changes.

Overview
When entire repo mirror create <github-url> runs without [cluster-host], an interactive terminal now loads clusters from the control plane and picks one (single-select, jurisdiction default pre-selected, prompt skipped if only one cluster)—aligned with entire repo clone.

Non-interactive use is unchanged: aws-us-east-2.entire.io with no catalog fetch. Explicit [cluster-host] still wins. resolveOneShotClusterHost / pickOneCluster handle fetch, auto-pick, and cancel guards; a test locks the script path.

Pull request overview

This PR restores interactive cluster selection for the one-shot entire repo mirror create <github-url> flow when [cluster-host] is omitted, matching the “prompt only when there’s a choice” behavior used elsewhere (while preserving the stable non-interactive default for scripts).

Changes:

• Added resolveOneShotClusterHost / pickOneCluster to prompt for a cluster in interactive terminals (auto-selecting when only one cluster exists).
• Updated repo mirror create help text and argument handling to use the new interactive cluster resolution when appropriate.
• Added a unit test to lock in the non-interactive behavior (no catalog lookup; fixed defaultClusterHost).
