## Problem
`TYPE_CHECKING` is used inconsistently across Python tests.
## Summary of changes
- Update `ruff`: 0.7.0 -> 0.11.2
- Enable TC (flake8-type-checking):
https://docs.astral.sh/ruff/rules/#flake8-type-checking-tc
- (auto)fix all new issues
## Problem
`pytest` 6 truncates error messages and this is not configured.
It's fixed in `pytest` 7, it prints the whole message (truncating limit
is higher) if `--verbose` is set (it's set on CI).
## Summary of changes
- `pytest` and `pytest` plugins are updated to their latest versions
- linters (`black` and `ruff`) are updated to their latest versions
- `mypy` and types are updated to their latest versions, new warnings
are fixed
- while we're here, allure updated its latest version as well
Temporarily disable `test_seqscans` for remote projects; they acquire
too much space and time. We can try to reenable it back after switching
to per-test projects.
Increase table size four times to fix the following error:
```
______________________ test_seqscans[remote-100000-100-0] ______________________
test_runner/performance/test_seqscans.py:57: in test_seqscans
assert int(shared_buffers) < int(table_size)
E assert 536870912 < 181239808
E + where 536870912 = int(536870912)
E + and 181239808 = int(181239808)
```
536870912 / 181239808 ≈ 2.96
Fix `test_seqscans` by disabling statement timeout.
Also, replace increasing statement timeout with disabling it for
performance tests. This should make tests more stable and allow us to
observe performance degradation instead of test failures.
Newer version of mypy fixes buggy error when trying to update only boto3 stubs.
However it brings new checks and starts to yell when we index into
cusror.fetchone without checking for None first. So this introduces a wrapper
to simplify quering for scalar values. I tried to use cursor_factory connection
argument but without success. There can be a better way to do that,
but this looks the simplest
More rows, and test with serial and parallel plans. But fewer iterations,
so that the tests run in < 1 minutes, and we don't need to mark them as
"slow".
