* style: pre-commit fixes
* fix: adapt to the ruff 0.16 default rule set
The hook update pulled in ruff 0.16, which expanded its default rules and
autofixed `self: S -> S` to `-> Self`. That fix added a runtime
`typing_extensions` import to setup_helpers.py, which must stay
dependency-free; it broke every test job whose environment does not supply
that package. The import is now guarded by TYPE_CHECKING.
Also replace the `exec` in docs/conf.py with an importlib module load,
parenthesize implicit string concatenations in list literals, mark unused
unpacked variables with a leading underscore, and make noxfile.py
executable to match its shebang.
The remaining new rules are silenced per-file, with reasons: the chrono
tests check naive local time on purpose, and the other rules conflict with
how the tests are written.

* Explain type_caster_enum_type_enabled, copyable_holder_caster_shared_ptr_with_smart_holder_support_enabled, move_only_holder_caster_unique_ptr_with_smart_holder_support_enabled in Upgrade guide.
* Add a small section for py::bind_vector, py::bind_map & py::smart_holder
* Fix tiny oversight: Reference back to the current release v2.13 (not v2.12)
* Remove sentence: Using self._pybind11_conduit_v1_() ... should keep extension compatibility.
This isn't true, because we also modernized `PYBIND11_PLATFORM_ABI_ID`
(which I believe was absolutely necessary). I think it'll be too complicated
to explain that here, and there is a mention in the Upgrade guide.
