Bumps httpcore2 from 2.9.1 to 2.10.0.

Release notes

Sourced from httpcore2's releases.

v2.10.0

Highlights

🚀 Performance and memory improvements

  • Sending large HTTP/2 request bodies no longer copies the body quadratically - sending a 256 MiB body went from ~36s to under 0.1s (pydantic/httpx2#1127).
  • SSE parsing is up to 35x faster on highly fragmented streams (pydantic/httpx2#1117).
  • Cookie extraction is now skipped for responses without a Set-Cookie header, making typical requests roughly 8% faster (pydantic/httpx2#1107).

🕸️ WebAssembly / Emscripten support

httpx2 now runs on Pyodide / Emscripten, using a JavaScript fetch-based transport defined in httpx2-jsfetch (pydantic/httpx2#1119, pydantic/httpx2#1114). Thanks @​hoodmane!

…ch pins

Brings in #348 and #349, which move httpx2 and httpcore2 to 2.12.0 and
close five Dependabot advisories (GHSA-8xx6-hgc6-gc2m and
GHSA-7mj9-2mp8-4m2p high, three medium).

No CLI code change is needed for these, and the reason is worth recording:
httpx2 is not a runtime dependency. It arrives transitively through
`hatch` in the dev extra, so it is absent from the published wheel's
Requires-Dist and never reaches anyone installing socketsecurity from
PyPI. Nothing under socketsecurity/ imports httpx or httpcore, and the
only hatch commands this repository runs are `hatch version` and
`hatch build`, neither of which performs HTTP. The advisories describe
build-tooling exposure on developer machines and CI runners, not shipped
surface.

Verified against the release path rather than assumed: hatch version,
hatch build, twine check, and a no-deps wheel install with a bytecode
compile all pass on 2.12.0, as do the 568 unit and core tests.

Separately, the same investigation turned up three different pins for the
same build tooling: build-system.requires wanted hatchling 1.32.0, the dev
extra pulled 1.28.0 via hatch 1.18.0, and .github/actions/setup-hatch
installed hatchling 1.27.0 with hatch 1.14.0 -- so CI ran an older hatch
than local development. The artifact was never affected, because
`hatch build` resolves the backend in an isolated environment from
build-system.requires and the wheel records `Generator: hatchling 1.32.0`.
The composite action now matches the other two, verified by building in a
clean virtualenv with the new pins.
