The footnote reference and definition patterns used [^\]\s] which matches
any character except ] and whitespace. This incorrectly detected regex
negated character classes like [^\s...] in code blocks as footnotes,
causing parseMarkdownIntoBlocks to return the entire document as one block.
Updated patterns to use [\w-] to only match valid footnote identifiers
(alphanumeric, underscore, hyphen).
Added regression tests to prevent this issue from recurring.
* fix: don't treat $$ inside code blocks as math delimiters
Code blocks can contain $$ as shell syntax (e.g., pstree -p $$ for current PID).
The math block merging logic was incorrectly counting $$ inside code blocks,
causing subsequent content to be merged as if it were part of a math block.
Added tracking of previous token type to skip math merging when the previous
block was a code block.

* Fix: TypeScript type mismatch at line 89 in `index.ts`: the visitor function's `index` parameter is typed as `number | undefined`, but the `visit` function expects `number | null`. The `undefined` type is not assignable to `number | null`.
This commit fixes the issue reported at /vercel/path0/packages/streamdown-cjk/index.ts:89
## TypeScript type incompatibility in visitor callback
**What fails:** TypeScript compiler fails during DTS (type definitions) build in `packages/streamdown-cjk/index.ts` at line 89
**How to reproduce:**
```bash
cd packages/streamdown-cjk
pnpm build
```
**Result:**
```
index.ts(89,3): error TS2769: No overload matches this call.
Overload 1 of 2, '(tree: Root, check: "link", visitor: BuildVisitor<Root, "link">, reverse?: boolean | null | undefined): undefined', gave the following error.
Argument of type '(node: Link, index: number | null, parent?: Parent) => number | undefined' is not assignable to parameter of type 'BuildVisitor<Root, "link">'.
Types of parameters 'index' and 'index' are incompatible.
Type 'number | undefined' is not assignable to type 'number | null'.
Type 'undefined' is not assignable to type 'number | null'.
```
**Root cause:** The visitor callback function passed to the `visit()` function from `unist-util-visit` was declaring the `index` parameter as `number | null`, but the visitor can also receive `undefined` as the index value. The `BuildVisitor` type signature expects the callback to accept `number | null | undefined` to properly match the library's API.
**Fix:** Updated the `index` parameter type annotation on line 89 from `number | null` to `number | null | undefined` to match the actual possible values that the visitor receives and the expected `BuildVisitor` type signature.
