Migrate guideline notes/tips/exceptions to markdown callouts

[Copilot]

This updates the remaining guideline rules that still used inline **Tip:** / **Note:** / **Exception:** markers to the newer markdown callout format already used by rule 0105. It also preserves readable rendering for both site and PDF output, including a consistent treatment for exception-style callouts.

• Content migration

  • Converted legacy inline callout labels across _rules/*.md to markdown alerts.
  • Updated multiline examples so code blocks remain part of the callout.
  • Standardized exception-style guidance as IMPORTANT alerts while retaining an Exception / Exceptions heading in rendered output.

• Site rendering

  • Added lightweight client-side transformation for Jekyll-rendered pages, where the markdown engine does not natively style GitHub alert syntax.
  • Added callout styling for note/tip/important/warning/caution variants.
  • Styled exception callouts distinctly without introducing a nonstandard alert type.

• PDF/build compatibility

  • Added alert translation in Build/Build.cs so the Pandoc-based document build renders callouts as readable blockquotes with headings instead of raw [!TIP] markers.

• Repo hygiene

  • Extended .gitignore for Build/bin and Build/obj so generated build artifacts are not picked up by future changes.

Example of the migrated rule format:

> [!TIP]
> Deconstruction also works in `foreach` loops:
>
> ```csharp
> foreach ((int key, int value) in dictionary)
> {
>     Console.WriteLine($"{key}: {value}");
> }
> ```
