Fix MCP publisher action

[JakeSCahill]

This pull request updates the MCP publishing workflow and related files to improve validation, error handling, and versioning for MCP server releases. The main focus is on enhancing the .github/workflows/publish-mcp.yaml workflow, updating the server version in the MCP server code, and bumping the version in server.json. The changes improve reliability and traceability of MCP registry publishing.

Workflow improvements and validation:

• Added validation steps to check that server.json exists, is valid JSON, and contains required fields before proceeding with publishing. This helps prevent publishing invalid configurations. [1] [2]
• Improved error handling and logging throughout the workflow, including checks for download failures, missing secrets, and publishing errors. Informative messages are displayed for each step. [1] [2] [3]
• Added a publication verification step to summarize the published server details after a successful publish.

Versioning and file updates:

• Changed the server versioning scheme in server.json to include the date, PR number, and commit SHA for better traceability of releases.
• Updated the default SERVER_VERSION in netlify/edge-functions/mcp.js to 1.0.0, matching the new release.

Workflow triggers and naming:

• Updated workflow triggers and job names to reflect new file locations and responsibilities, such as monitoring netlify/edge-functions/mcp.js and renaming the job to validate_and_bump_version_on_pr.
