Adds two new fields to ClientConfig:
- decoder: ResponseDecoder (default: PydanticDecoder())
- middleware: tuple[Middleware, ...] (default: ())

Both fields have defaults so existing construction paths are unchanged.
The PydanticDecoder default factory introduces a constructor-time
dependency from config.py on decoders/pydantic.py — acceptable since
pydantic is a hard dep.

Adds src/httpware/client.py with the AsyncClient skeleton:
- keyword-only __init__ resolving defaults for transport (Httpx2Transport),
  decoder (PydanticDecoder), middleware (()), timeout (Timeout()), and
  limits (Limits())
- _normalize_timeout helper for float→Timeout coercion
- _build_body helper for the upcoming HTTP method shortcuts
- _UNSET sentinel for the upcoming with_options method
- from_url classmethod factory
- middleware chain composed via compose() at construction; result stored
  in self._dispatch
- _owns_transport flag set to True (views from with_options will set False)

No HTTP methods yet (Task 3). Construction is side-effect-free —
Httpx2Transport's lazy init means no httpx2.AsyncClient() is created
until the first request.

Adds the eight public HTTP method shortcuts plus the helpers they share:
- _resolve_url for httpx-style base_url prefix join
- _build_request for default+per-call header/param merging
- _send for the dispatch + optional decode wiring
- 8 methods × 2 @overload declarations each (None vs type[T] for the
  response_model parameter) — total 16 overload stubs
- get/head/options/delete take no body params; post/put/patch add json
  and content (mutually exclusive — TypeError if both)
- request takes a leading positional method parameter

Lint-rule alignment:
- json: Any is refactored to a recursive `JsonValue` type alias rather
  than suppressed
- **kwargs: object on from_url (forwards heterogeneous args, doesn't
  read them) — no `Any` needed
- _UNSET sentinel typed `object` instead of `Any`
- `import typing` + `typing.Any` for the genuinely-heterogeneous
  internal `dict[str, typing.Any]` in extensions
- ASYNC109 suppressed per-line on each `timeout: Timeout | float | None`
  parameter with a justification comment (HTTP-method config-value
  timeout is not asyncio.timeout territory) — global ignore avoided so
  future code that should use asyncio.timeout still gets caught
- pylint.max-args raised to 10 globally (HTTP API methods naturally
  have many kwargs)

18 tests cover: URL resolution (relative, absolute, no base_url), default
merging (headers, params), body resolution (json→serialized,
content→passthrough, both→TypeError), per-call Content-Type override,
and one parametrized test per method confirming the wire-method string.

…ignore

The previous commit suppressed ASYNC109 per-line on each of the 24 HTTP
method signatures plus _send — same justification 25 times. Replaced with
a single per-file-ignores entry in pyproject.toml that centralizes the
"HTTP-method config-value timeout is not asyncio.timeout territory"
justification in one comment. Same scope of suppression, less noise.

Future code in other files that has `async def f(..., timeout=...)`
without justification still gets flagged.

Three tests verify the decoder wiring established in Task 3:
- response_model=None returns the raw Response (no decoder call)
- response_model=Foo invokes the configured decoder and returns Foo
- a user-supplied decoder= overrides the default PydanticDecoder

No production code changes; the plumbing was implemented as part of the
HTTP method shortcuts.

Adds tests/test_client_typing.py with typed assignments that exercise
each overload variant on get, post, and request. Wrong @overload
declarations would cause ty to reject the assignments. Runs as part of
`just lint-ci`'s ty check pass.

Includes a one-line runtime test so coverage sees the file is reachable.

Adds __aenter__ (returns self) and __aexit__ (calls transport.aclose()
if self._owns_transport). Three tests pass: aenter returns self, the
context manager closes the transport on exit, and double-close is safe
(Httpx2Transport.aclose is idempotent).

The view test (test_view_async_with_does_not_close_transport) stays
failing until Task 7 implements with_options.

Adds with_options(...) returning a new AsyncClient sharing the same
transport with selected config overrides. Uses the _UNSET sentinel so
None is a valid override value distinct from "not specified".

Adds _from_view classmethod that bypasses __init__ to construct a view
client (sets _owns_transport=False so __aexit__ is a no-op). The view's
middleware chain is re-composed against the shared transport.

with_options allowlist: base_url, default_headers, default_query, timeout,
decoder, middleware. limits and transport are intentionally NOT overridable
(both bind to the transport, which is shared).

Five new wiring tests cover: middleware execution per request, view re-
composes with new middleware, view inherits parent middleware when unset,
view shares the transport reference, view _owns_transport is False. The
previously-failing lifecycle test (view __aexit__ no-op) now passes.

Side effects of raising pylint.max-args = 10 globally:
- errors.py: two existing `# noqa: PLR0913` are now redundant (function
  signatures with 6-7 args are under the new threshold).
- test_client_response_model.py: `# ty: ignore[unknown-argument]` was
  defensive and turned out unused with the actual pydantic model used.

Also runs ruff format on client.py and test_client_methods.py.

…imeout

Adds tests for the previously-uncovered with_options override paths
(base_url, default_headers, default_query, decoder) plus a per-call
timeout test that verifies `timeout=` propagates into the Request's
extensions dict. Brings src/httpware/client.py to 100% line coverage,
addressing the final review's coverage concern.
