Add Lua filter support (pandoc.luaFilters) for admonition rendering

[Copilot]

Docusaurus-style admonitions (::: note, :::warning, etc.) pass through Pandoc unprocessed because Pandoc has no built-in knowledge of that syntax. Pandoc's Lua filter mechanism is the correct extension point for this.

Changes

• package.json: New pandoc.luaFilters setting — array of absolute paths to Lua filter files, default []
• src/extension.ts: New getLuaFilters() reads the setting and builds --lua-filter="<path>" args; appended to the Pandoc command (both standard and Docker modes) only when non-empty
• README.md: New "Lua Filters" section documenting the setting with a Docusaurus admonitions example
• test/suites/extension.test.ts: New Lua Filters Tests suite — single filter, multiple filters, empty list, and render workflow integration cases

Usage

// .vscode/settings.json
{
  "pandoc.luaFilters": [
    "/path/to/admonition-filter.lua"
  ]
}

Produces: pandoc "doc.md" -o "doc.html" --lua-filter="/path/to/admonition-filter.lua"

This is intentionally general — any community or custom Lua filter works, not just admonition-specific ones.

This section details on the original issue you should resolve

<issue_title>Admonition support</issue_title>
<issue_description>I am using this extension with a Docusaurus project, and my markdown uses Admonitions. Unfortunately, those aren't rendering nicely.

Note that I am using Markdown Admonitions that adds support for Docusaurus style fenced divs to the markdown preview.</issue_description>

Comments on the Issue (you are @copilot in this section)

@ChrisChinchilla @whitford-olmst I wasn't aware this was something Pandoc could handle, especially from something that defines its own "standards", such as Docusaurus, but I will look into it… Though I can't promise it will actually be possible.
