chore(deps): bump httpx2 from 2.7.0 to 2.12.0 in the uv group across 1 directory

[dependabot]

Bumps the uv group with 1 update in the / directory: httpx2.

Updates httpx2 from 2.7.0 to 2.12.0

Release notes

Sourced from httpx2's releases.

v2.12.0

Highlights

🛡️ Bounded response decompression

httpx2 now decodes gzip, deflate, Brotli, and Zstandard responses incrementally. Each decode step emits at most 1 MiB, so streaming a highly compressed response no longer requires materializing an entire inflated network chunk in memory (pydantic/httpx2#1126).

📦 Shared Zstandard API

Python 3.13 and earlier now use backports.zstd, which provides the same bounded incremental decompression API as compression.zstd on Python 3.14 and later (pydantic/httpx2#1146).

httpx2

Changed

• Use backports.zstd for Zstandard decoding on Python 3.13 and earlier by @​Kludex in pydantic/httpx2#1146

Fixed

• Bound peak memory while streaming compressed responses and close response streams when decoding fails by @​Kludex in pydantic/httpx2#1126

httpcore2

No changes since 2.11.0. Version bumped to stay in lockstep with httpx2.

Full Changelog: pydantic/httpx2@v2.11.0...v2.12.0

v2.11.0

Highlights

🌐 Public origin API

httpx2 now includes an immutable and hashable Origin value object, available through URL.origin. It provides normalized scheme, host, and effective port comparisons without including URL paths, queries, fragments, or credentials (pydantic/httpx2#1134).

🛠️ Request compatibility and validation

• Explicit Transfer-Encoding headers now take precedence over body-derived Content-Length headers (pydantic/httpx2#1137).
• Deprecated status code aliases are available again (pydantic/httpx2#1135).
• Multipart part headers are validated before serialization (pydantic/httpx2#1142).

httpx2

Added

• Add the public Origin value object and URL.origin property by @​Kludex in pydantic/httpx2#1134

Changed

• Require Brotli 1.2.0 or later for the brotli extra by @​Kludex in pydantic/httpx2#1141
