name: Sync from ClickHouse

# Daily: copy the latest lexer sources from the main ClickHouse repository. If they
# changed, rebuild lexer.wasm, regenerate the derived modules, run the tests, commit,
# tag a patch release, and create a GitHub release. Publishing the release to npm is
# a separate, manually-triggered step - see publish.yml.
