feat: http.request v0.1.0 — generic HTTP client

First release. Pure-WASM HTTP client built on waki 0.5 for
F∆I flow steps that need to call REST APIs.

Capability: http.request@0.1.0

Inputs: method (GET/POST/PUT/PATCH/DELETE/HEAD/OPTIONS),
url, headers (JSON object string), body (UTF-8).

Outputs: status (decimal text), headers (JSON object), body
(UTF-8 lossy).

Permissions: net: *. The wildcard is deliberate — operators
clamp to specific hosts via their operator-policy ceiling.

6 unit tests on the headers-input parser (empty / strings /
numbers coerced / non-object rejected / nested rejected /
malformed JSON rejected).

Bundle: target/wasm32-wasip2/release/http_request.wasm
(~120 KiB stripped).

v0.2.0 candidates: http.request-bytes for binary payloads,
per-request timeout / retry inputs, cookie-jar.
