Fixes #225.

Problem

#218 upgraded the pinned Ruff action from 0.15.22 to 0.17.3. Ruff's default enabled rules changed: master now reports 150 violations across existing files, and unrelated PRs inherit the failure (including #223). [tool.ruff] also set no target-version, so pyupgrade-style fixes (e.g. UP017 → datetime.UTC, Python 3.11+) would ignore the declared python = "^3.8" support.

Master run: https://github.com/ActivityWatch/aw-server/actions/runs/42245017977

Fix

• Set target-version = "py38" under [tool.ruff], matching tool.poetry.dependencies.python.
• Pin the previous default selection explicitly (E4, E7, E9, F) and move the existing ignores into the supported [tool.ruff.lint] table, so future Ruff bumps can't silently widen it.

Keep the newer pinned action. Lint stays enabled, and there are no per-file exclusions or --fix --unsafe-fixes mass-applies. New rule families (FA100, UP, I001, …) can be adopted deliberately in separate PRs.

Verification

• Reproduced on unmodified master: Ruff 0.17.3 reports 150 errors; 0.15.22 passes.
• After the change, uvx ruff@0.15.22 check . and uvx ruff@0.17.3 check . both pass.
• The effective enabled rule codes are identical under both versions (58 rules), and the resolved target is 3.8 for linter and formatter.
• Negative control: an undefined-name stdin fixture still fails with F821.
• Configuration only; no application code changes.

[Low impact] This configuration-only change appears safe to merge.

Summary

The PR makes Ruff’s lint selection explicit without changing the pinned action.

• The lint job keeps its rule set steady across Ruff upgrades.

🤖 AI code review

The PR sets target-version = "py38" under [tool.ruff] in pyproject.toml. It adds [tool.ruff.lint] with an explicit selection of E4, E7, E9, and F, and moves the existing E402 and E501 ignores into that table.

This is a fix(...) PR but no test files are included in the diff. Erik's feedback: 'where is the repro & fixes they are supposed to catch' (gptme#3441), 'that measurement should come with a regression test' (gptme#3446). Add a test that would have caught this bug. (Advisory: Erik merged all such PRs but consistently requested tests.)

Add a test file that reproduces the bug before the fix and passes after it.

Pushed an empty commit to retrigger CI — the macOS job was CANCELLED on the previous run (not FAILED). All other checks (ubuntu, windows, typecheck, lint, format, CodeQL, Greptile) are ✅ on 7b0b5595. This PR is a dependency for #209, #223, and other PRs on old bases: master's lint is currently failing on the same pre-existing issues these PRs expose.
