Charles KWON OhJun 384f957f4e feat(httpserver): HTTP_SERVER_START / _STOP with PRG handler dispatch ...

Adds hbrtl_ext/httpserver — a Five RTL extension that exposes a
single-process HTTP server controlled entirely from PRG.

Wire contract:
  HTTP_SERVER_START(cAddr, cHandlerFunc)  → blocking; returns NIL or cErr
  HTTP_SERVER_STOP()                      → graceful shutdown

PRG handler signature:
  FUNCTION OnRequest( hReq ) -> hResp
    hReq:  method, path, query, headers (hash), body, remote_addr
    hResp: status (default 200), headers (hash), body

Each request runs on its own hbrt.Thread via vm.NewThread(), the same
pattern pgserver uses for connection isolation. Handler panics are
caught and turned into a 500.

The package is wired into fnode's defaultRTL list so any build that
doesn't override --rtl picks it up automatically.

Verified end-to-end with app/echo_server.prg: GET/POST against :8089
return JSON envelopes with the correct method, path, query, body
length, remote_addr, and roundtripped user-agent header.

The mod_harbour-compatible AP_* surface (AP_METHOD, AP_RPUTS,
AP_JSONRESPONSE, etc.) will sit on top of this dispatcher in
sub-phase 1a.3 as PRG, not Go.
