chore(deps): bump the uv group across 1 directory with 2 updates

[dependabot]

Bumps the uv group with 2 updates in the / directory: cryptography and h2.

Updates cryptography from 49.0.0 to 50.0.0

Changelog

Sourced from cryptography's changelog.

50.0.0 - 2026-07-31

* **SECURITY ISSUE**:
  :func:`~cryptography.hazmat.primitives.serialization.pkcs7.pkcs7_decrypt_der`
  and its PEM and S/MIME variants no longer expose distinguishable errors or
  timing when unwrapping a ``RecipientInfo``'s ``encryptedKey``, which could
  act as a Bleichenbacher oracle for callers that decrypt untrusted messages.
  A random key is now substituted on failure, as described in :rfc:`3218`.
  Credit to **@X1AOxiang** for reporting the issue. **CVE-2026-69247**
* Deprecated Diffie-Hellman key exchange over finite fields (FFDH).
  Everything FFDH is deprecated, including the types in
  ``cryptography.hazmat.primitives.asymmetric.dh`` and loading FFDH keys or
  parameters with the key loading APIs. Users should migrate to a more
  modern key exchange algorithm.
* Added ``xof()`` class methods to
  :class:`~cryptography.hazmat.primitives.hashes.SHAKE128` and
  :class:`~cryptography.hazmat.primitives.hashes.SHAKE256` for constructing
  algorithm instances configured for use with
  :class:`~cryptography.hazmat.primitives.hashes.XOFHash`.
* The :mod:`X.509 verification <cryptography.x509.verification>` APIs are now
  considered stable and are subject to our API stability policy.
* Added the :doc:`/cobblestone` recipe, an implementation of the
  Cobblestone-128 and Cobblestone-256 instantiations of the `C2SP
  chunked-encryption specification
  <https://c2sp.org/chunked-encryption>`_ for streaming authenticated
  encryption of large messages.
* Parsing a Signed Certificate Timestamp list now rejects encodings that
  carry trailing bytes after the list or after an individual SCT, instead of
  silently ignoring them.
* Added support for using :class:`~cryptography.x509.Name` as a field type in
  the :doc:`/hazmat/asn1/index` module.
* Loading a public key or an EC private key now rejects DER where the
  ``subjectPublicKey`` (or EC ``publicKey``) ``BIT STRING`` declares a non-zero
  number of unused bits, instead of silently ignoring it.
* Parsing a CRL entry's ``InvalidityDate`` extension now rejects a
  ``GeneralizedTime`` that carries fractional seconds or another non-DER form,
  matching the strict encoding already required for every other X.509 time
  field.
* :func:`~cryptography.x509.ocsp.load_der_ocsp_request` and
  :func:`~cryptography.x509.ocsp.load_der_ocsp_response` now reject a request
  or response whose ``version`` field is not ``v1``, the only version defined
  by RFC 6960, matching the version validation already performed when loading
  certificates, CSRs and CRLs.
* :class:`~cryptography.hazmat.primitives.hashes.XOFHash` is now supported
  when building against AWS-LC.
* HMAC (and therefore PBKDF2-HMAC) with SHA-3 hashes is now supported when
  building against AWS-LC.
* Diffie-Hellman (:doc:`/hazmat/primitives/asymmetric/dh`) is now supported
  when building against AWS-LC.

Updates h2 from 4.3.0 to 4.4.1

Changelog

Sourced from h2's changelog.

4.4.1 (2026-08-03)

Bugfixes

• Performance improvement: remove consumed frames in-place from data buffer.
• Reject duplicate Host headers in request headers. Thanks to Sunand Mohan for the report.

4.4.0 (2026-07-23)

API Changes (Backward Incompatible)

• Support for Python 3.9 has been removed.
• Support for PyPy 3.9 has been removed.
• Stream.end_stream() now raises NoSuchStreamError or StreamClosedError exceptions, instead of a generic KeyError.
• Duplicate content-length headers with different values now raise ProtocolError. Previously, the first content-length header was accepted and later conflicting values were ignored. Thanks to Harshal Parekh for the report.
• Parse content-length headers according to RFC9110 grammar for numbers (1*DIGIT). Thanks to Arkadiusz Marta for the report.
• backfill from v4.3.0 Convert emitted events into Python dataclass, which introduces new constructors with required arguments. Instantiating these events without arguments, as previously commonly used API pattern, will no longer work.

API Changes (Backward Compatible)

• Support for Python 3.14 has been added.
• H2Connection.receive_data now accepts any byte-like object that implements the buffer protocol, such as bytes, bytearray, and memoryview. Existing bytes callers are unaffected.
• Align CONNECT pseudo-header validation with RFC 9113 s8.3 and RFC 8441 s4. Ordinary CONNECT now requires :method=CONNECT and :authority, and forbids :scheme/:path. Extended CONNECT (e.g., WebSocket) requires :scheme, :path, :authority plus :protocol. (PR #1309)
• Fix incorrect substring matching of secure header in cookie and :method.

Bugfixes

• Fix to allow sending 0 bytes on a stream even if the flow control window is negative.
• Reject non-zero SETTINGS_ENABLE_PUSH values received from servers.
