fix(claude): add direct binary download fallback

When native installer fails (e.g., network timeouts in claude binary),
fall back to direct binary download from GCS bucket. This bypasses the
'claude install' command which has internal network timeout issues.

Tested: Successfully installs when native installer times out.
