Add `js/` (`@bytecodealliance/wrpc`), a dependency-free, transport-agnostic JavaScript codec for the wRPC wire format, mirroring `wrpc-transport`'s `value.rs` and default framing: - `t`/`types` build the structural WIT type tree; - `value` encodes/decodes component-model values (a jco-compatible mapping); - `wit` parses inlined WIT text back into the type tree; - `frame` builds an invocation's request bytes and decodes its results. The ESM source runs directly in the browser and is publishable to npm; it ships a hand-written `.d.ts`, JSDoc, `node --test` round-trip tests and a `tsc` typecheck. Use the codec in the `wasi:keyvalue` web example: the UI imports it from `/wrpc` (served via `ServeDir`) and drops the hand-rolled byte encoding, removing the 127-byte request/response size limits.
