Integrate Espressif's QEMU fork for virtual ESP device management: - QemuManager component with 5 MCP tools (start/stop/list/status/flash) - Config auto-detects QEMU binaries from ~/.espressif/tools/ - Supports esp32, esp32s2, esp32s3, esp32c3 chip emulation - Virtual serial over TCP (socket://localhost:PORT) transparent to esptool - Scan integration: QEMU instances appear in esp_scan_ports results - Blank flash images initialized to 0xFF (erased NOR flash state) - 38 unit tests covering lifecycle, port allocation, flash writes
