v1.1.0

Add opt-in mode: "form" generation with typed form results, exact-case ordered
fields, and a telemetry-only encoded body. Validate form transport, UTF-8, limits,
and complete telemetry families. Default header generation and material reuse remain
compatible. Accept the six required headers plus an optional fresh same-family a0,
preserving returned names and values. Reject incomplete, duplicate, mixed-family and
unsafe header sets. Form results remain exactly six fields. Reject mismatched response
transports and redact form values in inspection.
