Issue

Summary

  • Bump the minimum supported Python to 3.11 in pyproject.toml (requires-python, classifiers, [tool.ty.environment]) and drop 3.10 from every CI matrix in .github/workflows/_checks.yaml (lint, type-check, unit tests, integration tests, e2e tests).
  • Apply ruff autofixes unlocked by the version bump across src/ and tests/: UP017 (datetime.timezone.utcdatetime.UTC), UP035 (typing_extensions.Selftyping.Self), UP041 (asyncio.TimeoutError → builtin TimeoutError).
  • Refresh uv.lock — the resolver drops the 3.10-only backport packages (backports-asyncio-runner, exceptiongroup, importlib-metadata, zipp).

Why

3.10 reaches end-of-life soon, and the upcoming apify-client v3 already requires >=3.11. Landing the version drop on its own first keeps the v3 client-upgrade series small and reviewable.

BREAKING CHANGE

Python 3.10 is no longer supported. Users on 3.10 must upgrade to 3.11+ before pulling the next SDK release.

Python 3.10 reaches end-of-life soon and apify-client v3 (next major)
will require Python >= 3.11. Bumping the minimum now lets the SDK use
3.11+ stdlib idioms (`datetime.UTC`, `typing.Self`, `TimeoutError`
alias) and unblocks the apify-client v3 adoption series.

- `pyproject.toml`: `requires-python = ">=3.11"`, drop the 3.10
  classifier, set `[tool.ty.environment]` to 3.11.
- `.github/workflows/_checks.yaml`: drop 3.10 from lint, type-check,
  unit-test, integration-test, and e2e-test matrices.
- Refresh `uv.lock` (removes 3.10-only backport packages).
- Apply ruff autofixes unlocked by the version bump (UP017, UP035,
  UP041) across `src/` and `tests/`.

BREAKING CHANGE: Python 3.10 is no longer supported.

@janbuchar Starting with SDK v4, I'll split the big PRs into more, smaller reviewable ones. Let's start with this.

The previous ruff autofix (UP017) hoisted `from datetime import UTC` to
module scope, but `main()` functions passed to `make_actor` are serialized
and run on the Apify platform without access to enclosing-module imports,
so they raised `NameError: name 'UTC' is not defined` at runtime.
