feat: smoke example + arduino bb_wifi backends + bb_http transport rewrite (#159)

Stand up examples/smoke/ as the consolidated home for portable bb_*
exercise across boards and frameworks. The same src/smoke_app.c compiles
unchanged on every env; per-framework entry shims (entry_arduino.cpp,
entry_espidf.c later) call into smoke_app_setup/loop. Initial env:
r4_wifis3 (Arduino UNO R4 WiFi). ESP-IDF envs land in a follow-up PR.

Add platform/arduino/bb_wifi/ with two backends selected by build flag:
- bb_wifi_r4.cpp (-DBB_WIFI_BACKEND_R4) — WiFiS3 / on-board ESP32-S3
- bb_wifi_cc3000.cpp (-DBB_WIFI_BACKEND_CC3000) — Adafruit_CC3000 shield

Both implement the full bb_wifi public surface plus the new transport
API (bb_wifi_listen / bb_wifi_accept / bb_conn_*).

Rewrite platform/arduino/bb_http/bb_http_arduino.cpp to consume the
transport API exclusively — bb_http is now radio-agnostic on Arduino.
The route table, response-buffer batching, and dispatch logic are
unchanged; only the socket layer moves.

Migrate examples/arduino-uno-cc3000/ to use bb_wifi_cc3000 instead of
driving CC3000 directly in main.cpp. Adafruit_CC3000 only supports the
AVR SPI API, so this example stays the dedicated CC3000 hardware-
verification target on classic Uno; folding it into smoke as r4_cc3000
on the R4 Minima is blocked on a forked or replacement library.

Wire r4_wifis3 into Makefile + CI smoke matrix.

Hardware-verified earlier in the session: R4 WiFi associates, /ping
returns pong over the new bb_http+transport path. Local builds clean
on r4_wifis3, arduino-uno-cc3000, esp32-wroom-32; host tests 352/352.
