chore(deps): remove unused google>=3.0.0 dependency

[omergulen]

Summary

Remove the google>=3.0.0 dependency from setup.py and requirements.txt. This package is unused and was added by mistake.

Background

The dependency was introduced accidentally in commit 7b3ec4a7 (2020-11-09) when google-api-python-client was shortened to google during the package rebranding from ttvcloud to volc.

The google package on PyPI (by Mario Vilas) is a Google Search scraper — it has nothing to do with google.protobuf. All from google.protobuf imports in this codebase are satisfied by the protobuf package, which is already a separate dependency.

Verification

A search of the entire codebase confirms:

• Zero files import anything from the google PyPI package
• Every from google.protobuf import resolves via the protobuf package
• Neither google-api-python-client nor google was ever used in any service module

Impact

• Removes an unused, unmaintained (last release: 2020) transitive dependency
• Also drops the unnecessary transitive dependency on beautifulsoup4
• No functional changes — no code references this package

Changes

• setup.py: removed "google>=3.0.0" from install_requires
• requirements.txt: removed google>=3.0.0
