docs: Discovery Stage 2 framing, revision 3
Three corrections, each to something revision 2 asserted without
checking the mechanism it was reasoning about. All three verified in
the tree.

A ROUND-TRIP FREEZES NOTHING. Revision 2 proposed pinning the legacy
variant with an encode/decode round-trip. That test uses the SAME types
on both sides, so adding a field to `MinibufferPrompt` leaves it
passing while every v12-v22 peer in the field breaks. The existing
`minibuffer_prompt_round_trips_through_postcard` (src/protocol.rs:2363)
is precisely that shape, and there are NO literal byte fixtures
anywhere in the protocol tests today --- checked, not assumed. Only
`assert_eq!(encoded, LEGACY_BYTES)` against bytes captured now can fail
when the encoding changes. Two fixtures, open and clear, matching the
shapes the semantic test already covers so the corpus is not a fresh
judgement call.

THE CACHE HAZARD I DESCRIBED CANNOT HAPPEN. Revision 2 argued for a
per-variant cache key on the grounds that a peer reconnecting at a
different version could have its first message suppressed as a
duplicate. `SemanticRenderState::for_peer(frontend_id,
negotiated_protocol_version)` is created PER PEER with its version
baked in on attach (src/daemon.rs:2080) and removed on detach (:1591),
so a cache never spans two versions and reconnecting creates a fresh
state. One per-peer cache stands; the selection is a producer gate,
`peer_knows_minibuffer_rows`, alongside the four such gates that
already exist (:1410-1435). The test for the impossible condition is
REMOVED rather than written --- a test that cannot fail passes forever
and teaches the next reader that the hazard is real.

The matched open/close family requirement is independent of caching and
stands unchanged.

"THE NAME MUST SURVIVE" IS NOT ACHIEVABLE. Prompt plus typed input
consume the width budget first, so the remaining suffix space can be
too small for even the bare name --- and revision 2's rule would then
have forced a partial name, which reads as a DIFFERENT command. The
rule is now ordered: if the whole name does not fit, omit the suffix
entirely; only once it fits is a description attempted; if the
description does not fit whole, drop it. The guarantee becomes "never a
partial name", which is achievable, rather than "the name always
survives", which is not. Witnessed at three widths.
