refactor: rename firmware directory to weather_clock
clock_ntp_ota_v1.9/ → weather_clock/ (version no longer baked into path) clock_ntp_ota_v1.9.ino → weather_clock.ino Version is tracked in config.h (FIRMWARE_VERSION), not in filenames. Updated references in README, CONTRIBUTING, and docs/INSTALLATION.md. Note: forks using the old path will need to sync this rename before submitting new PRs.
