Alex PetrochenkoandClaude Sonnet 4.6 3a34244ac8 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.

Alex PetrochenkoandClaude Sonnet 4.6 29d7c7f8ad chore: remove monolithic src/ copy, firmware/ is now canonical 
src/clock_ntp_ota_v1.9.ino was a duplicate of firmware/clock_ntp_ota_v1.9/
that had already drifted out of sync. Removing it eliminates the need to
patch both copies on every PR.

Updated CONTRIBUTING.md build path to point to firmware/clock_ntp_ota_v1.9.
