* feat: migrate firmware to xiaozhi-fonts 2.0.0 * fix: restart scrolling subtitles on text change * docs: add AGENTS.md for project overview, architecture, rules, and commands - Introduced AGENTS.md to document the XiaoZhi voice-assistant firmware architecture, required rules for development, board configuration process, and validation steps. - Included detailed sections on project structure, commands for building and testing, and authoritative documentation references. * feat: finalize glyph push protocol * fix: remove stale emoji font include * build: use xiaozhi-fonts 2.0.0 * fix: decouple custom fonts from glyph push * refactor: improve wake word invocation handling - Introduced BeginWakeWordInvoke method to streamline the wake word processing flow. - Updated HandleWakeWordDetectedEvent to utilize the new method, ensuring proper state transitions and scheduling. - Enhanced error handling to prevent the device from getting stuck in the connecting state. - Refactored audio channel management to improve responsiveness during wake word detection. --------- Co-authored-by: Xiaoxia <terrence.huang@tenclass.com>
