Add the WebMCPify agent skill 🤖🤖🤖

[TueJon]

Description

Adds the WebMCPify agent skill as a vendored, self-contained skill with its references and templates. The skill gives Copilot a gated workflow to inventory, integrate, verify, and audit WebMCP tools while preserving unrelated application behavior.

WebMCP is a proposed web standard currently available through a Chrome origin trial; the skill retains that status disclosure and feature-detects the API. The canonical source and MIT license are recorded in the skill frontmatter.

Verification

• Read and followed CONTRIBUTING.md and repository instructions.
• Confirmed no existing WebMCPify/WebMCP issue, PR, or repository-tree entry.
• Tested with the official GitHub Copilot CLI v1.0.73 on a disposable Book Finder app: Copilot loaded webmcpify, proposed two bounded tools, and stopped at the required human manifest-approval gate; the Git tree remained clean.
• Ran the canonical WebMCPify checks (17 tests passed).
• Ran npm run skill:validate.
• Ran npm start and verified docs/README.skills.md is current.
• Ran bash eng/fix-line-endings.sh and git diff --check.
• Targets main.

Type of Contribution

• New skill file.

Additional Notes

The vendored content matches the canonical skill; the only distribution metadata additions are the canonical source URL and repository-required YAML quoting.
