Subject: [PATCH] =?UTF-8?q?=F0=9F=93=9D=20docs(wire-schema):=20schema.v1?=
 =?UTF-8?q?=20+=20error.v1=20JSON=20Schema=20(fb-27)?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

schema.v1: full introspection report shape with required fields for
wire / capabilities / models / stats. capabilities object enumerates
all 10 flag names (current 6 true + future 4 false) as required keys.

error.v1: 7-code enum + permissive details object. Real emitted
details shapes documented in description (per-code context varies and
some fields are interim until IoFailure / OpTimeout typed signals
land in follow-up).
