chore: add .gitattributes to normalize line endings

[SamErde]

TL;DR

Adds a repository-level .gitattributes so text files are stored with LF, preventing CRLF files from being committed from Windows and tripping linters (yamllint flagged this twice during review of #1899).

Details

• * text=auto stores LF in the repository for all detected text files.
• YAML, shell, JS/TS, JSON, and markdown files are forced to LF in the working tree too, since CI tooling (yamllint, actionlint, prettier) expects Unix endings.
• PowerShell files (.ps1, .psm1, .psd1, .ps1xml) are stored with LF but keep platform-default working-tree endings so Windows contributors retain a native editing experience.
• Common binary asset types are marked binary.

Scope note: this PR intentionally does not renormalize existing files (no git add --renormalize), keeping the diff to a single new file. Existing CRLF blobs will be corrected naturally as files are next modified. A follow-up bulk renormalization can be done later if desired.

Follow-up to review feedback on #1899.

Summary by CodeRabbit

• Chores
  • Added repository-wide line-ending rules to keep text files consistent across platforms.
  • Standardized common source and documentation formats to use LF endings.
  • Marked common binary asset types as non-text, while treating SVG files as text for improved handling.

Pull request overview

Adds a repository-level .gitattributes to normalize line endings, ensuring text files are stored as LF in the repo to prevent CRLF-related CI/linter noise (notably on YAML/tooling-sensitive files), while keeping a Windows-friendly working-tree experience for PowerShell contributors.

Changes:

• Introduces * text=auto for repo-wide text normalization to LF.
• Forces LF checkout for common tooling-sensitive text formats (YAML, shell, JS/TS, JSON, Markdown).
• Marks PowerShell file types as text (repo-normalized) without forcing working-tree EOL, and marks common asset formats as binary.
