fix(cli): retry site eval after startup navigation

[shabooboo006]

Summary

• Retry transient Runtime.evaluate target/navigation failures in the site command.
• Re-resolve the target tab before retrying so a tab created during Chrome startup can settle.
• Limit retries to a short startup window to avoid replaying long-running site adapters after they may have performed side effects.

Duplicate check

• Searched open PRs for the exact Inspected target navigated or closed error: no matches.
• Reviewed related open PRs feat(cli): use system default browser with real user profile + nodeExec adapter mode #190, feat(daemon): auto-reconnect when CDP WebSocket closes #193, and fix: bypass CORS for site adapters via about:blank execution #159; they address browser launch/CDP reconnect/CORS paths, not this initial site eval navigation failure.
