…#473)

* build(deps): bump Python to 3.12, drop typed_ast and ruff-replaced linters

- Require Python ^3.12 (from ^3.7.2)
- Drop typing-extensions: Concatenate/ParamSpec now in stdlib typing (3.10+)
- Drop black and flake8: superseded by ruff (already in pre-commit config)
- Bump pytest ^6 → ^8, Sphinx * → ^9 (requires Python 3.12)
- Unpin pydata-sphinx-theme (sphinx-book-theme#711 long resolved)
- Drop allow-prereleases on web3 (stable 6.x line is sufficient)
- Loosen click ^8.0.3 → ^8
- Update build backend: poetry.masonry.api → poetry.core.masonry.api
- CI: test and typecheck jobs now use Python 3.12
- Move [tool.ruff] → [tool.ruff.lint] (deprecation fix)
- Silence unused _token_two variable (second-token approval was never wired up)

Note: web3 7.x upgrade deferred (major async-first rewrite, breaking API changes).

* ci: fix Poetry 2.x compat and bump docs to Python 3.12

- Remove deprecated 'installer.modern-installation' setting (removed in Poetry 2.0)
- Bump docs.yml from Python 3.8 to 3.12 to match the new package floor
  (Python 3.8 + cytoolz 0.12.1 failed to build via Cython under PEP 517)

* fix(makefile): replace flake8/black with ruff lint/format targets

flake8 and black were removed as direct dependencies in the Python 3.12 dep bump;
the Makefile still referenced them. Ruff already handles both roles.

* fix(deps): add explicit floors for Python 3.12-incompatible Cython packages

cytoolz 0.12.1, frozenlist 1.3.3, yarl 1.8.2, and multidict 6.0.4 all
declare python-versions=>=3.6 but have no pre-built cp312 wheels, causing
Cython compilation failures when installing under Python 3.12.

Add explicit minimum constraints in pyproject.toml so poetry resolves to
versions that ship cp312 wheels:
- cytoolz >=0.12.3  (locked to 1.1.0)
- frozenlist >=1.5.0  (locked to 1.8.0)
- multidict >=6.0.5  (locked to 6.7.1)
- yarl >=1.10.0  (locked to 1.24.5)

propcache 0.5.2 added as a new transitive dep from yarl 1.24.5.

* fix(deps): add aiohttp floor to unblock Python 3.12 CI

aiohttp 3.8.4 (transitive via web3) has no cp312 wheels and fails
to build from source on Python 3.12 — PyLongObject.ob_digit was
removed in 3.12. Added aiohttp = ">=3.9.0" (first release with
cp312 wheels) as a direct dependency constraint; poetry re-locked
to 3.14.3 which ships cp312 wheels.

This fixes all 6 failing CI jobs (build + 4 test matrix + typecheck).

* fix(deps): pin setuptools<82 and bump doc theme versions for Python 3.12 CI

Two independent CI failures after the Python 3.12 bump:

- Test/typecheck jobs: eth-keyfile (pulled in via web3->eth-account) still
  imports pkg_resources, which setuptools dropped starting in 82.0.0 (last
  shipped in 81.0.0). eth-account>=0.12 fixes this upstream but requires
  hexbytes>=1.2.0, which conflicts with web3 6.x's hexbytes<0.4.0 pin — that
  needs the (deliberately deferred) web3 7.x migration. Pin setuptools<82 as
  a stopgap; also floor typing-extensions>=4.12.0, since 4.5.0 crashes under
  Python 3.12.13's stricter TypeVar base-class check (docs build failure).

- Docs build: sphinx-book-theme was resolving to 0.0.11 (a 2020-era release,
  incompatible with Sphinx 9's theme API — missing 'get_edit_url'). Floor it
  to ^1.1, which also pulls a compatible pydata-sphinx-theme (0.20.0).
  Along the way, Sphinx 9 hard-fails on the old implicit-%s extlinks caption
  format ("issue #" -> "issue #%s").

Verified locally: full install, docs build (make html), pytest collection
(250 tests), and mypy --pretty all pass in an isolated poetry venv.

* fix(deps): add ruff as explicit dev dependency

Makefile lint/format targets call `poetry run ruff` but ruff was
absent from [tool.poetry.dev-dependencies]. A fresh `poetry install`
would succeed without it, making `make lint` fail immediately.

Lock file regenerated with Poetry 2.3.2 / Python 3.12.3.
