deps: bump tokenizers from 0.22.2 to 0.23.1 (#3149)

Bumps [tokenizers](https://github.com/huggingface/tokenizers) from
0.22.2 to 0.23.1.

<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/huggingface/tokenizers/releases">tokenizers's
releases</a>.</em></p>
<blockquote>
<h2>Release v0.23.1</h2>
<h2>TL;DR</h2>
<p><code>tokenizers 0.23.1</code> is the first proper stable release in
the <code>0.23</code> line — <code>0.23.0</code> only ever shipped as
<code>rc0</code> because the release pipeline itself was broken (Node
side hadn't shipped multi-platform binaries since 2023, Python side was
on <code>pyo3 0.27</code> without free-threaded support).
<code>0.23.1</code> is the version where everything actually goes out
the door together: full Node multi-platform wheels for the first time in
years, Python 3.14 (regular <strong>and</strong> free-threaded
<code>3.14t</code>), full type hints for every Python class, and a stack
of measurable perf wins on the BPE / added-vocab hot paths.</p>
<p>There is no functional <code>0.23.0</code> published — we tag
<code>0.23.1</code> directly so users don't accidentally pull a
never-shipped version.</p>
<hr />
<h2>🚨 Breaking changes</h2>
<ul>
<li><strong>Drop Python 3.9</strong> (<a
href="https://redirect.github.com/huggingface/tokenizers/issues/1952">#1952</a>)
— <code>requires-python = &quot;&gt;=3.10&quot;</code>; 3.9 users stay
on <code>0.22.x</code>.</li>
<li><strong><code>add_tokens</code> normalizes <code>content</code> at
insertion</strong> (<a
href="https://redirect.github.com/huggingface/tokenizers/issues/1995">#1995</a>)
— re-saved <code>tokenizer.json</code> may differ in the
<code>added_tokens</code> block. Existing files load unchanged.</li>
<li><strong>Type stubs are precise</strong> (<a
href="https://redirect.github.com/huggingface/tokenizers/issues/1928">#1928</a>,
<a
href="https://redirect.github.com/huggingface/tokenizers/issues/1997">#1997</a>)
— methods that returned <code>Any</code> now return real types;
<code>mypy --strict</code> may surface previously-hidden errors. Stub
layout also moved from <code>tokenizers/&lt;sub&gt;/__init__.pyi</code>
to <code>tokenizers/&lt;sub&gt;.pyi</code>. This breaks the surface of
some of the processors like <code>RobertaProcessign</code>'s
<code>__init__</code> .</li>
<li><strong>3.14t-only</strong>: setters/getters return
<code>PyResult&lt;T&gt;</code> because of
<code>Arc&lt;RwLock&lt;Tokenizer&gt;&gt;</code>; a poisoned lock
surfaces as <code>PyException</code> instead of a panic.</li>
</ul>
<hr />
<h2>⚡ Performance — measured locally on this Mac, not lifted from
PRs</h2>
<p>Run with <code>cargo bench --bench &lt;name&gt; -- --save-baseline
v0_22_2</code> on <code>v0.22.2</code>, then <code>--baseline
v0_22_2</code> on <code>v0.23.1</code>. Numbers are point-in-time wall
clock on a single laptop; relative deltas are what matters, absolute
numbers will differ on CI hardware.</p>
<h3>Added-vocabulary deserialize — the headline win (<a
href="https://redirect.github.com/huggingface/tokenizers/issues/1995">#1995</a>,
<a
href="https://redirect.github.com/huggingface/tokenizers/issues/1999">#1999</a>)</h3>
<p><code>bench: improve added_vocab_deserialize to reflect real-world
workloads</code> (<a
href="https://redirect.github.com/huggingface/tokenizers/issues/2000">#2000</a>)
is now representative of how transformers actually loads tokenizer.json
files. The combined effect of <code>daachorse</code> for the matching
automaton plus the normalize-on-insert refactor is enormous on this
workload:</p>

<p>The BPE per-thread cache PR (<a
href="https://redirect.github.com/huggingface/tokenizers/issues/2028">#2028</a>)
shows much larger wins on highly-parallel workloads (+47–62% at 88+
threads on a server box, per the PR's own measurements on Vera).
Single-thread batch numbers above are flat or slightly improved because
cache-hit overhead was already low without contention.</p>
