Fix QEMU version detection and remove unsupported ESP32-S2

Sort glob results when auto-detecting QEMU binaries to reliably
pick the newest version. Previously filesystem ordering could select
an older build (8.2.0 instead of 9.0.0), missing ESP32-S3 support.

Remove ESP32-S2 from CHIP_MACHINES — the Espressif QEMU fork has
no esp32s2 machine type.

Document QEMU emulation in README and improve tool descriptions

Add QEMU section to README with install instructions and tool reference.
Enrich MCP tool docstrings with workflow context, cross-references to
related tools, and guidance on when to use each tool — these descriptions
are read by the calling LLM to decide tool selection.

Add QEMU ESP32 emulation support

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
