Code review: Apply clang-format and add .gitignore

[Copilot]

Comprehensive code review and formatting cleanup of the codebase.

Changes

• Formatting: Applied clang-format to 28 source files for consistency with .clang-format and CODE_STYLE.md

  • Fixed line breaks, indentation, and spacing
  • Standardized multi-line statement formatting

• Repository hygiene: Added .gitignore to exclude build artifacts, compilation databases, and IDE files

Example

Before:

wlan_emu_print(wlan_emu_log_level_dbg,
    "%s:%d: mac_str : %s rssi : %d noise : %d bitrate : %d\n",
    __func__, __LINE__, to_mac_str(heart_beat_data->mac, mac_str), heart_beat_data->rssi,
    heart_beat_data->noise, heart_beat_data->bitrate);

After:

wlan_emu_print(wlan_emu_log_level_dbg,
    "%s:%d: mac_str : %s rssi : %d noise : %d bitrate : %d\n", __func__, __LINE__,
    to_mac_str(heart_beat_data->mac, mac_str), heart_beat_data->rssi, heart_beat_data->noise,
    heart_beat_data->bitrate);

No functional changes. Static analysis and security scans completed with no issues.
