Subject: [PATCH] fix(fetch): preserve redirects during streaming parser
 suspension

Attach the committed navigation response before publishing the initial phase-one-blocked Page snapshot, matching replacement Document installation.

Add renderer and CLI regressions for initial and resumed snapshots, gated response bodies, relative and absolute redirects, trace and readiness modes, and cached responses.
