+ * HTTP — minimal HTTP/1.1 server library (Phase 1)
+ *
+ * Goals for Phase 1:
+ * - HTTP/1.1 request parsing (request-line, headers)
+ * - Message body handling via Content-Length and Transfer-Encoding: chunked
+ * - Persistent connections (keep-alive) with Connection: close handling
+ * - Simple handler callback API: handler(req) -> res
+ * - No TLS, no pipelining, no compression, no auth (to be added later)
+ *
+ * API overview:
+ *   class HTTP(number port)
+ *     fun start(this, handler)
+ *       - handler: function taking `req` map and returning `res` map
+ *
+ *   Request map `req` fields:
+ *     - method: string
+ *     - target: raw request-target (string)
+ *     - path: path part without query (string)
+ *     - query: query string without '?' (string)
+ *     - version: "HTTP/1.1" or "HTTP/1.0"
+ *     - headers: map<string,string> (lower-cased header names)
+ *     - body: string (for Phase 1; streaming may arrive later)
+ *     - remote_fd: number (client socket fd)
+ *
+ *   Response map `res` fields:
+ *     - status: number (e.g. 200)
+ *     - reason: optional string (defaults from common codes)
+ *     - headers: optional map<string,string>
+ *     - body: optional string (defaults to empty)
