v2.5.2

What's Changed

• fix: build the ESP32-S3 firmware with ESP-IDF 5.5.5 and the optimized PERF (-O2) profile by @muness in #215

Improved: The production firmware now uses ESP-IDF's performance compiler optimization (-O2) instead of the debug (-Og) profile. This produces optimized code for normal operation.

Updated: ESP-IDF 5.5.5. This is Espressif's stable bugfix release for the 5.5 line.

Full Changelog: v2.5.1...v2.5.2
