* feat: add MAC address filter for ESP32 CSI collection In multi-AP environments, CSI frames from different access points get mixed together, corrupting the sensing signal. Add transmitter MAC filtering so only frames from a specified AP are processed. Implementation: - csi_collector: filter in wifi_csi_callback by comparing info->mac against configured MAC; log transmitter MAC in periodic debug output - csi_collector_set_filter_mac(): runtime API to enable/disable filter - Kconfig: CSI_FILTER_MAC option (format "AA:BB:CC:DD:EE:FF") - NVS: "filter_mac" 6-byte blob overrides Kconfig at runtime - nvs_config: parse Kconfig MAC string at boot, load NVS override - main: apply filter from config after csi_collector_init() When no filter is configured (default), behavior is unchanged — all transmitter MACs are accepted for backward compatibility. Fixes #98 Co-Authored-By: claude-flow <ruv@ruv.net> * chore: add CLAUDE.local.md to .gitignore Local machine configuration (ESP-IDF paths, COM port, build instructions) should not be committed to the repository.
