The review's remaining items:
- _done_with_value's rejection branch now caps the _check_done_value diagnostic
through _cap_message (a reason embedding a hostile class name could otherwise
push the done frame past the host's 64 MiB parse cap, misreporting an
invalid-output run as a worker-exit).
- The settlement note (en + zh) updates three stale facts (load bound is now
parse-cap minus envelope at 67108800; the sink goes directly through the
bound primitives); the fd-3 protocol note (en + zh) no longer claims the
package ships protocol without the runtime; FRAME_ENVELOPE_BYTES' JSDoc and
_cap_message's docstring follow the new bound.
Pairings re-recorded.
