## What changed
- Fetch ChatGPT account access and attach `cyber_trusted_access` under
`openai/entitlementContext` when an installed or selected plugin explicitly
requests it from a local, read-only stdio tool with no arguments.
- Reject caller-supplied entitlement context on direct MCP calls, and fall back
to an `unknown` status when access cannot be verified or the account changes
during the lookup.
- Count entitlement lookup time against the MCP tool-call timeout.
## Testing
- Cover eligible calls plus unowned, remote, HTTP, mutable, argument-bearing,
API-key, undeclared, direct, and account-switch cases in core and app-server
integration tests.

## What changed
- Add `TrustedAccessContext` to fetch account-bound cyber verified-access grants and attach them as host-owned `openai/entitlementContext` metadata.
- Replace caller-supplied entitlement metadata and return an `unknown` status when authentication, identity consistency, response validation, size limits, or the lookup deadline cannot be verified.
- Add `HttpResponseBodyStream::from_chunks` for lightweight in-memory streaming clients.
## Testing
- Cover grant mapping, unsupported authentication, account and workspace changes, malformed or oversized responses, duplicate programs, and lookup timeouts.
