Add esp32s3 as a supported board that shares the ESP-IDF installation with esp32. The ESP32 toolchain is parameterized by chip target so each variant builds in its own directory with its own sdkconfig. Key changes: - Parameterize the ESP32 toolchain by Esp32Target (toolchain names, build directory, ROM linker scripts) - Build the runtime for esp32s3 in ports/esp32/build-esp32s3 with sdkconfig.esp32s3 generated from sdkconfig.defaults - Enable BLE 4.2 advertising API and skip Classic BT memory release on non-ESP32 targets - Disable memory protection (CONFIG_ESP_SYSTEM_MEMPROT_FEATURE) so executable RAM can be allocated on ESP32-S3 - Add NULL check in bs_memory_init() with a clear error message - Share the ESP-IDF clone between esp32 and esp32s3 setups - Add unit tests for setup, remove, and flash-runtime with esp32s3 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01U2xPxvDJAipDisXeFvWoAh
Add 'bscript board build-runtime <board>' to build the runtime without flashing it. This is useful when the board is connected to a different host: build on the development machine, copy the build directory, and flash with esptool.py on the target host. - Add build-runtime.ts with the new command handler - Add abstract buildRuntime() and build() to FlashRuntimeHandler - Export FlashRuntimeHandler, ESP32FlashRuntimeHandler, and getFlashRuntimeHandler so the new command can use them - Register the command in the CLI entry point - Add unit tests and documentation Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01U2xPxvDJAipDisXeFvWoAh
