[Repo Assist] test: fix all ruff lint errors in tests/test_observable/; remove from ruff exclude

[github-actions]

🤖 This PR was created by Repo Assist, an automated AI assistant.

Summary

Fixes all 153 ruff lint errors in tests/test_observable/ and removes that directory from the ruff exclude list in pyproject.toml. This is the final ruff-cleanup stage — the ruff exclude list now has no test directories.

Changes

pyproject.toml

• Remove tests/test_observable from [tool.ruff] exclude

tests/test_observable/ — 153 ruff errors fixed:

• E741 (13): Renamed ambiguous variable l → left / items / timers in test_amb.py, test_skipuntil.py, test_takeuntil.py, test_timeinterval.py, test_groupjoin.py
• E721 (1): Replaced type(err) == asyncio.CancelledError with isinstance(err, asyncio.CancelledError) in test_fromfuture.py
• E501 (37): Long test assertion lines (marble data) suppressed with # noqa: E501 where needed, docstring lines wrapped at 88 chars
• UP032/UP031/UP004/UP035/I001/F401 etc. (rest): Auto-fixed (f-strings, useless object inheritance, deprecated imports, unsorted imports, etc.)

Validation

• uv run ruff check . → All checks passed!
• uv run pyright → 0 errors, 0 warnings, 0 informations (pyright exclude for tests/test_observable and tests/test_scheduler remains — strict-mode pyright fixes are a separate effort)

Note on pyright

The pyright exclude for tests/test_observable and tests/test_scheduler remains in place — strict pyright mode reveals ~7000 type errors there, which require a dedicated cleanup effort.
