Document Docusaurus markdownlint exceptions

[Brett Curtis (brettcurtis)]

Documents the repo-specific markdownlint disables in .github/copilot-instructions.md:

• MD041 — Docusaurus pages start with YAML front matter, not a heading
• MD046 — MDX admonitions and components mix fenced and indented code blocks

Found during a workspace-wide audit against the platform instructions, which only list MD013/MD033/MD045 as disabled. The two extras are intentional Docusaurus accommodations and now documented as such.

Also includes trailing-newline fixes that pre-commit surfaced on 9 pre-existing docs pages.

Release Notes

• Documentation

  • Enhanced documentation with comprehensive guidance on Markdown linting rules and platform-specific exceptions. Added detailed explanations of how these configurations support the documentation framework's unique formatting requirements and content presentation capabilities.

• Style

  • Improved documentation formatting consistency by removing trailing whitespace from documentation files across multiple platform modules. These changes ensure standardized document structure and presentation throughout the documentation set.

In @.github/copilot-instructions.md:
- Around line 5-13: The PR adds a "Markdown Lint" section and new exceptions
MD041 and MD046 to .github/copilot-instructions.md which violates the
requirement that this file be identical across platform repos; remove the entire
"Markdown Lint" section (the table and any references to MD041 and MD046) so the
file matches the canonical copilot-instructions.md used by the platform team,
leaving only the original, approved disabled rules (MD013, MD033, MD045).
