Pull request overview

This PR imports the initial GitHub Copilot “store” content for docs-desktop, including reusable skills (PowerShell automation), prompts, agents, and writing-style instructions intended to standardize docs edits and snippet workflows.

Changes:

• Added two redirect-focused skills: one to create redirect entries and one to sort redirection JSON files.
• Added multiple prompts and agent definitions for template validation, metadata targeting, snippet migration/upgrade, link-text refresh, and editing workflows.
• Added repo-specific documentation guidance (Copilot instructions + Markdown writing style rules) for desktop docs.
