ci(conformance): integrate MCP server conformance test pipeline

[anubhav756]

Description

This PR integrates the official MCP conformance testing framework to automatically validate the strict protocol compliance of MCP Toolbox server.

Changes

• Adds a GitHub Action that builds and spins up the server binary, then targets it with the MCP conformance runner.
  • It uses a conformance-baseline.yml file to track known gaps without blocking contributors.
• Adds a 6:00 AM cron job that runs the tier-check audit tool.
  • It automatically creates and updates a self-maintaining dashboard issue (labeled periodic-failure) so maintainers can easily track operational SLA and label requirements needed for Tier 1 status.

Note

We have opened an upstream PR to fix the Repository Health table, in the generated GitHub issue, in the official conformance tool: modelcontextprotocol/conformance#239

Code Review

This pull request introduces a conformance-baseline.yml file to the root directory. The reviewer suggests moving this file to a more appropriate location, such as the tests/ or ci/ directory, to maintain a clean project structure and align with existing organizational patterns.

Consider moving the conformance-baseline.yml file to a more appropriate directory, such as tests/ or a dedicated ci/ folder, to maintain a clean root directory. This aligns with the project's structure where integration tests are grouped in the tests/ directory.
