* feat: add qemu emulator
* chore: use current dir instead of cloning repo
* Add QEMU emulator tooling under tools/qemu
tools/qemu/tasmota-qemu.sh builds the current Tasmota checkout for an ESP32
PlatformIO env and boots it under an Espressif QEMU fork on an amd64 host:
serial console, and a browsable web UI via the WiFi-capable fork.
NET_WIFI=1 tools/qemu/tasmota-qemu.sh # build -> image -> wifi QEMU -> web UI
Notes:
- Builds the local working tree (no clone); artifacts and QEMU forks live under
a gitignored tasmota-qemu/ at the repo root.
- ESP32-only helper; no Tasmota core source is changed.
See tools/qemu/README.md for commands, env vars, and panic-debugging notes.
* chore: cleanup
