Replace black, isort, flake8 and pyupgrade with ruff

[zigpy-review-bot]

Problem

pre-commit can no longer be installed in this repo. The fsouza/autoflake8 hook repository has been deleted from GitHub:

An unexpected error has occurred: CalledProcessError: command: ('/usr/bin/git', 'fetch', 'origin', '--tags')
    remote: Repository not found.
    fatal: repository 'https://github.com/fsouza/autoflake8/' not found

The last CI run, in April, passed. The shared workflow installs hooks fresh whenever it has no cached pre-commit environment, and GitHub evicts caches that go unused for 7 days, so the next CI run will fail the same way.

Changes

• Hooks: drop black, flake8 (with its plugin pins), isort, pyupgrade and autoflake8 in favour of ruff-check + ruff-format (ruff-pre-commit v0.16.9). debug-statements stays; mirrors-mypy goes from v1.20.1 to v2.3.1.
• [tool.isort] and [tool.flake8] become [tool.ruff]. The rules are B, C, E, F, I, SIM, UP, W, the set zigpy-znp uses, with max-complexity = 25, plus YTT because flake8-2020 was installed. E501 stays ignored and the tests/* per-file ignores are unchanged. The isort settings carry over.
• requirements_test.txt: drop isort, black, flake8 and Flake8-pyproject, and bump ruff==0.0.261 to ruff==0.16.9 to match the hook.
• Remove the unused flake8 problem matcher. The shared CI workflow only loads python.json.
• Second commit: the resulting fixes. Mostly autofixes: import sorting and pyupgrade rewrites for the Python 3.11 floor (typing.Dict → dict, timezone.utc → UTC, str.format → f-strings). The old pyupgrade hook ran without a --pyXX-plus flag, so these had not been applied. By hand: the remaining %-formatting (struct format strings and __str__ methods), a %-formatted LOGGER.exception call → lazy logging arguments, explicit zip(strict=...) keeping the current behaviour, and exception chaining for re-raised errors.

Verification

• pre-commit run --all-files passes on Python 3.14. On dev it fails while installing hooks.
• Tests: 47 passed.

Context

This is one of a set of draft PRs that align the pre-commit setup of the zigpy libraries on ruff (ruff check + ruff format), which zigpy, zha, zha-device-handlers, zigpy-znp, zigpy-ota and zigpy-ziggurat already use. The same change is proposed for bellows, zigpy-deconz, zigpy-xbee, zigpy-zigate and zigpy-cli, plus small ruff config fixes in zigpy and zigpy-ziggurat.

The commits are kept separate so parts can be dropped or moved into their own PR. Maintainers can ask the bot for that, or for any other change, by commenting @zigpy-review-bot <request> on this PR.
