esp_hosted ships a CLI -- an esp_console REPL on the serial console --
enabled by default, and every ESP32-P4 arduino build was carrying it.
On a cloud-compiled sketch it is worse than useless: its "host>" prompt
interleaves with the user's own serial output, and its console task polls
a UART that in the emulator never blocks, pinning one HP core at
priority 23 and defeating the engine's idle fast-forward. Found while
bringing up the P4's esp_hosted WiFi companion, where it made a
mostly-idle guest emulate two orders of magnitude slower than it should.
Appended in the same esp32p4 block that pins the rev0 mask ROM, for the
same reason: it is a property of running on the emulator's terms, not a
user choice.
