refactor: rename firmware directory to weather_clock

Browse Source 
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.
