[dependabot]

Bumps the all-dependencies group with 1 update: tiktoken-rs.

Updates tiktoken-rs from 0.12.0 to 0.12.1

Release notes

Sourced from tiktoken-rs's releases.

v0.12.1

A maintenance release that refreshes upstream tiktoken and restores compatibility with the declared Rust 1.85 minimum. Existing public function signatures are unchanged.

Changes

• Refresh the vendor snapshot to OpenAI tiktoken 0.14.0 and align regex dependencies. GPT-5 tokenizer lookup follows upstream's family-prefix matching. (#173)
• Use a 1,050,000-token context-window default for gpt-6* names. This adds context metadata only; GPT-6 tokenizer lookup and token-budget helpers remain unsupported. (#174)
• Fix Rust 1.85 compilation and the default-feature README doctest; test both default and all features across supported platforms. (#170)
• Replace lazy_static with the standard library's LazyLock. (#165)
• Clarify README instructions and remove release-specific wording. (#172)
• Fail release detection on registry errors and remove inactive upload jobs. (#171)

The minimum supported Rust version remains 1.85.

Thanks to @​Expyron for their first contribution in #165.
