chore: upgrade Vite Plus and KaTeX

[nperez0111]

Summary

• Upgrade Vite Plus from 0.2.9 to 0.3.3 (Rolldown 1.2.9) and align Vitest pins.
• Upgrade KaTeX to 0.18.9 across the math package, docs, playground, and interoperability examples.
• Remove the KaTeX lexer patch now that the Rolldown fix is included.
• Support both legacy and prefixed KaTeX equation-tag classes in the equation-number CSS selector.

Verification

• vp run -r build
• vp run --filter @blocknote/math-block test (35 passed, 10 skipped)
• git diff --check

Summary by CodeRabbit

• Bug Fixes
  • Improved equation-number spacing for math content rendered with KaTeX.
• Maintenance
  • Updated KaTeX across documentation, examples, and the playground, and refreshed several internal tooling versions.

📝 Walkthrough

Walkthrough

KaTeX dependency ranges changed across packages, documentation, and examples. The equation-number padding selector now matches .katex-tag. Workspace overrides and the vite-plus catalog range also changed.

Changes

KaTeX updates

Layer / File(s)	Summary
KaTeX version alignment docs/package.json, packages/math-block/package.json, examples/05-interoperability/06-converting-blocks-to-docx/*, examples/05-interoperability/07-converting-blocks-to-odt/*, playground/package.json, playground/src/examples.gen.tsx, patches/katex@0.16.47.patch, pnpm-workspace.yaml	KaTeX dependency ranges changed to ^0.18.9 in packages, documentation, and examples. The KaTeX patch mapping was removed from the workspace configuration. Regex strings in the patch file now use escaped Unicode ranges.
Equation-number styling packages/core/src/editor/Block.css	The equation-number padding selector now matches a direct .tag or .katex-tag child of .katex-html.

Workspace tooling updates

Layer / File(s)	Summary
Workspace version and patch settings pnpm-workspace.yaml	Vitest, @vitest/runner, and @vitest/mocker overrides changed to 4.1.11. The vite-plus catalog range changed to ^0.3.3. The @y/prosemirror patch mapping was reformatted.

_{A rabbit checks the math with care,
New KaTeX ranges settle there.
The tags now meet the padding rule,
Workspace versions shift in school.
I thump once, then hop away.}
