[dependabot]

Bumps json from 2.19.3 to 2.19.9.

Release notes

Sourced from json's releases.

v2.19.9

• Fix buffer overflow that could lead to a crash when writing JSON directly into an IO with JSON.generate(object, io). [CVE-2026-54696].

Full Changelog: ruby/json@v2.19.8...v2.19.9

v2.19.8

What's Changed

• Fix 1-byte buffer overread on EOS errors.
• Handle invalid types passed as max_nesting option.

Full Changelog: ruby/json@v2.19.7...v2.19.8

v2.19.7

What's Changed

• Fix some more edge cases with out of range floats.
• Ensure the string provided to JSON.parse can't be mutated during parsing.
• Add missing write barriers in State#dup.
• Further validate generator depth config.

Full Changelog: ruby/json@v2.19.6...v2.19.7

v2.19.6

What's Changed

• Cleanly handle overly large depth generator argument.
• Add missing write barrier in ParserConfig.

Full Changelog: ruby/json@v2.19.5...v2.19.6

v2.19.5

What's Changed

• Cap the parser to emit a maximum of 5 deprecation warnings per document. Emitting more is not helpful.
