release: patch cli, compiler, core, csr, syntax, validation

Typed, callable api blocks for .wrn files: sectioned request/response/error,
callable from client code as api.name(input), type-checked by tsc against the
route contracts.

Also two fixes found along the way: defineEndpoint never received its input
through the real router, so every typed endpoint was validating undefined; and
v.boolean() silently coerced any unrecognised string to false.
