fix(generate): don't escape < in multiline code blocks

[risu729]

Fixes jdx/mise#6949

---

Note

Update the markdown escape filter to detect fenced code blocks and avoid escaping within them.

• Markdown Rendering (lib/src/docs/markdown/renderer.rs):
  • Escape filter (escape_md):
    • Detects fenced code blocks using lines starting with ``` and tracks in_code_block state.
    • Skips HTML escaping (e.g., < to <) for lines inside fenced blocks; leaves fence lines unchanged.
    • Previously only excluded indented code blocks; now also respects fenced code blocks.

Pull request overview

This pull request attempts to fix escaping of < characters inside fenced code blocks (delimited by ```) in the markdown renderer. The change adds state tracking to detect when processing lines within fenced code blocks, so that HTML escaping can be skipped for those lines.

Key changes:

• Adds in_code_block boolean state variable to track whether currently inside a fenced code block
• Modifies the escape_md filter to toggle the state when encountering ``` fences
• Extends the early return condition to skip escaping when in_code_block is true

Bug: Indented code content incorrectly detected as fence delimiter

The check line.trim_start().starts_with("```") incorrectly matches lines that are content within indented code blocks (4+ spaces of indentation). In Markdown, fenced code block markers can only have 0-3 spaces of indentation; lines with 4+ spaces are indented code block content. If such content happens to contain "```", the in_code_block state gets toggled incorrectly, causing subsequent non-code text to skip `<` escaping when it shouldn't. The fence detection should either check the indentation condition first or validate that there are fewer than 4 leading spaces.

I didn't know this, should we support it?
