Adds opt-in PDF file handling to avoid conflicts with QuickLook's default PDF viewer while allowing users who prefer SumatraPDF to enable it.

Changes

• Plugin.cs: Cache Plugin.SumatraPDFReader.EnablePdfSupport setting during Init() and check it in CanHandle() for .pdf extensions (defaults to false)
• README.md: Document configuration file location and XML setting structure

Configuration

Users enable PDF support by creating/editing QuickLook.Plugin.SumatraPDFReader.config:

<?xml version="1.0" encoding="utf-8"?>
<Settings>
  <Plugin.SumatraPDFReader.EnablePdfSupport>true</Plugin.SumatraPDFReader.EnablePdfSupport>
</Settings>

Config location:

• Standard: %APPDATA%\pooi.moe\QuickLook\
• Portable: <QuickLook>\UserData\

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https /usr/lib/apt/methods/https (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_title>Use plugin as PDF too [REQUEST]</issue_title>
<issue_description>I would like to use this plugin as replacement for Quicklook PDF viewer. I know there is one based on WebView2 but I like Sumatra better.
I know a little coding but I don't know how to edit the project so I can make a fork or something like that </issue_description>

<agent_instructions>加一个quicklook常用的option选项支持（本插件内置的xml文件）是否打开PDF的支持，默认不打开</agent_instructions>

@emako I don't think it's a good alternative, but you can compile your own version.

The README says "Add this line to the configuration file" but the snippet is a full XML document (including XML declaration and root). This can mislead users who already have an existing config, since pasting the whole block would create invalid XML (duplicate root/declaration). Consider rewording to clarify whether users should create the file with this full content if it doesn't exist, or add only the <Plugin.SumatraPDFReader.EnablePdfSupport> element inside an existing node (and call it the plugin config file rather than the generic "QuickLook configuration file").
