Fixes #2060

Why

robusta --help crashes with ModuleNotFoundError: No module named 'cachetools' in installs whose dependency tree does not include the transitive chain (traceback: robusta/integrations/prometheus/utils.py line 5, from cachetools import TTLCache). This repo imports cachetools directly in five modules (runner/web.py, integrations/prometheus/utils.py, integrations/kubernetes/api_client_utils.py, core/sinks/robusta/dal/supabase_dal.py, core/sinks/robusta/robusta_sink.py) but only declared types-cachetools (stubs) in dev-dependencies; the runtime package arrived only transitively via google-auth/pyiceberg. Same class of bug as the tenacity entry above it, fixed the same way.

Summary

• Add cachetools = ^6.2.4 (matches the locked 6.2.4) to [tool.poetry.dependencies] in pyproject.toml.
• Regenerate poetry.lock with poetry lock (content-hash only, 1 line).
• Add tests/test_direct_dependencies.py: asserts cachetools is declared and TTLCache imports. The metadata test fails on main, passes with this change.

How to Test

python -m pytest tests/test_direct_dependencies.py tests/test_app_imports.py -q

Expected: 3 passed. Verified in Docker python:3.11-bookworm (repo CI version): poetry check --lock clean, 3 passed. New metadata test fails on unpatched pyproject.

Explanation

Issue #2060 requires robusta --help to avoid the reported cachetools import failure. pyproject.toml now declares cachetools = ^6.2.4 as a direct runtime dependency. tests/test_direct_dependencies.py checks the declaration and the TTLCache import used by the application. The reviewed summary supports the dependency fix. poetry.lock is excluded from review, so its contents are not assessed.

3.10, where tomllib is unavailable. Use the project’s declared toml dependency
or another Python 3.10-compatible parser, and adjust the TOML-loading calls in
