Devin FoleyandPaperclip 7703220d38 perf(github): narrow response authority reads (#17686)
Read current GitHub response identity and policy fields without transferring saved message bodies, instructions, or automatic policy wrappers. Preserve company predicates, shared locks, publication leases, malformed input handling, and stored content.

Verify workspace typecheck, server build, 414 selected GitHub tests, three focused browser cases, all 55 checks, and Apex 5/5. Preserve the original browser cleanup deadlock failure; always restore experiment settings while reporting cancellation errors.
