zeekay 999e2153b3 Type every wire: bytes, forms, streams, sockets, redirects, unions ...

A typed op could only take one JSON value and answer one, so uploads,
signed webhooks, form posts, YAML and merge-patch bodies, PDFs, SSE,
WebSockets, OAuth redirects and upstream relays stayed untyped routes
with no schema, tool, command or SDK method. Each is now a typed op and
its REST wire is unchanged.

Requests: a zip.Body field takes the body and Content-Type exactly as
sent; an In implementing Parser decodes itself; form: fields and
*zip.File parts bind url-encoded and multipart forms; cookie: binds a
request cookie as an in: cookie parameter. Consumes names the media.

Answers: zip.Body (bytes, filename, its own status and headers, a
Reader streams chunked), Verbatim[T] (a relay documented as T), Sse[T]
(events with keep-alive), Socket[M] (an upgrade after the contract
runs; 426 without one, 501 over ZAP), Redirect, CookieCoder, Produces,
and unions: a type whose OneOf method's results are the alternatives,
with Or[A,B] as the stock one filing each under the status it states.

Projections follow from the manifest: the document publishes binary
media, form schemas, x-events, x-socket with 101, 3xx with Location
and oneOf; MCP takes bytes as base64 and returns bytes, text or
collected events as tool content, listing a socket op in _meta as no
tool; the CLI reads --body @file|-, --field name=@file and --out,
prints events as they arrive and bridges a socket to stdin and stdout.
tools/list is ProjectMCP over the manifest, the projection MCPTools
already was.

Prose reaches promoted fields (filed under the declaring struct), a
type defined over another struct, and the type arguments of zip's
kinds and OneOf results; an instantiated generic is published under
its name followed by its argument names instead of an illegal
component key. The unused reflect-only document and tool builders go.
