Bump jsonschema from 0.51.0 to 0.54.0

[dependabot]

Bumps jsonschema from 0.51.0 to 0.54.0.

Release notes

Sourced from jsonschema's releases.

[Rust] Release 0.54.0

Added

• backend = SerdeJson on #[jsonschema::validator], generating a validator that reads serde_json::Value.
• PreparedDocument::unsatisfiable_pointers, listing every subschema no value satisfies.

Changed

• Canonicalization of unevaluated* beside dependentSchemas or if/then/else, which kept the document Raw.
• Canonicalization of not over patternProperties, which kept the document Raw.

Performance

• validate and iter_errors check each assertion keyword with the is_valid path and build an error only for a failing one.
• evaluate holds its output tree in one allocation instead of one per node.
• A pattern of ^\S*$ scans bytes instead of decoding every character.
• validate on properties beside a two-name required confirms both names in the pass that checks the properties, instead of looking each up first.
• A string enum compares an option's length and first and last eight bytes before its full text.
• A JSON Pointer segment is scanned for ~ and / eight bytes at a time before it is copied.
• Canonicalization cloning leaves per intersection and the definition map per settled target.

Fixed

• type: array with items and minItems/maxItems checking the built-in length bound even when a custom keyword overrides minItems or maxItems, so the bound was evaluated twice.
• A custom keyword overriding type, required or maxLength not replacing the built-in check for that keyword.
• A custom keyword overriding items, minLength, properties or additionalProperties leaving its sibling keywords unchecked.
• #[jsonschema::validator] generated code that named serde_json directly, so it needed the consumer crate to depend on serde_json too.
• Canonicalization of not over an object with properties, patternProperties and additionalProperties, which applied additionalProperties to the keys listed in properties.

[Python] Release 0.54.0

[0.53.0] - 2026-09-02

Added

• Location::segments, iterating the segments without collecting them.
• CanonicalizeOptions::prepare, canonicalizing any number of a document's subschemas by JSON Pointer, with the document indexed once.
• CLI: the --at POINTER flag of jsonschema canonicalize, canonicalizing only the subschema at that pointer without breaking its references into the rest of the document.
• CLI: jsonschema canonicalize reads YAML schemas (.yaml/.yml) as well as JSON.
• canonical::{ArrayView, IntegerView, NumberView, ObjectView, StringView, TypedGroupView}, the payload types of CanonicalView, so consumers can name them in signatures.

Fixed

• jsonschema-value failing to build with default-features = false.
• jsonschema-value failing to build for wasm32-unknown-unknown, which needs getrandom's wasm_js backend.
• Draft 4 type: integer accepting numbers written with an exponent, like 1e2.
• Draft 4 type: integer answering differently for the same number across representations.
• uniqueItems accepting 0 alongside -0.0 in arrays of more than 15 items.
