/**
* Whether `ctx` belongs to a protocol 2026-07-28 request. That revision has no
* session: each request carries its own `_meta` envelope, and the SDK lifts
* it into `ctx.mcpReq.envelope`. It does so on every era, though — a 2025-era
* client may send reserved `_meta` keys too — so envelope *presence* is not
* the test. What only a 2026-07-28 request carries is the protocol version
* key: the SDK requires it to classify a request as modern in the first
* place. Code that must choose between "per request" and "per connection"
* (client capabilities, log level) branches on this.
