fix(weather): remove duplicate visibility property and update manifest metadata

Remove deprecated `visibility` property in favor of `native_visibility`,
move `UnitOfLength` import to module-level, and update manifest.json
with correct codeowner, documentation URLs, weather dependency, and
bump version to 1.0.1.
