build(NoTicket): update dependencies for Python 3.10

[lorenzhs]

Now that the SDK requires Python 3.10, update dependencies and development tools to their latest compatible releases.

Update sqlparse to 0.6.0, which includes parser denial-of-service fixes. Adapt our CASE workaround to the new upstream block-stack splitter and add regressions for escaped semicolons and nested CASE expressions. The workaround is still needed pending sqlparse PR #839.

Also update AnyIO, Trio, mypy, pyfakefs, pytest and its plugins, pre-commit, Sphinx's Python 3.10-compatible floor, and formatting/lint hooks. Remove two ineffective fixture marks that pytest 9 rejects; the usage-tracker test retains its xdist grouping. Include the formatting changes required by the new Black release.

Validation on Python 3.10:

• Unit suite: 780 passed, 1 skipped.
• Usage-tracker integration tests with 6 xdist workers: 8 passed.
• All 219 integration tests collect.
• All pre-commit checks pass, including mypy 2.4.
• Documentation build succeeds with 29 existing warnings.
• Dependency audit of the 90 resolved runtime/dev/docs packages reports no known vulnerabilities.

Live database integration tests were not rerun locally.

Note

Medium Risk
Upgrading sqlparse and rewriting statement-splitting logic can change how multi-statement queries are parsed; dependency bumps (mypy 2, pytest 9) affect CI only but runtime parsing is user-facing.

Overview
Bumps runtime and dev dependencies for the Python 3.10+ baseline: sqlparse 0.6.0 (DoS fixes), AnyIO/Trio, mypy 2.x, pytest 9 and plugins, pre-commit/Sphinx floors, and refreshed pre-commit hooks (Black 26, isort 9, flake8 7.4, etc.). setup.cfg pins the new versions; the example notebook picks up Black-driven formatting only.

The main product change is adapting SQL statement splitting after the sqlparse upgrade: the old large _change_splitlevel monkeypatch is replaced by a thin wrapper that delegates to sqlparse’s splitter and only adds CASE tracking outside BEGIN blocks (still pending upstream PR #839). New unit tests cover CASE expressions with escaped semicolons in literals and nested CASE when splitting multi-statement SQL.

Test harness cleanup drops invalid @mark.xdist_group on module fixtures (pytest 9); usage-tracker parametrized tests keep their xdist group. A trivial # type: ignore spacing fix in base_cursor.py.
