Release v2.7.0

[github-actions]

Prepare release v2.7.0

Changes

• [build] Switch to ESLint 9.x #87
• [example] Align the codicon version used in the example with the version expected by @eclipse-glsp/client #90
• [diagram] Fix spurious "No Custom Document found" errors by forwarding onDidChangeCustomDocument events only for documents owned by the provider when multiple GlspEditorProvider instances share a GlspVscodeConnector #92
• [mcp] Add support for Model Context Protocol integration, bridging the GLSP-announced MCP server into the VS Code MCP definition provider API #91
  • Opt-in via an MCP server configuration on the connector; the announced endpoint is registered on startup and deregistered on extension dispose.
  • The Workflow example demonstrates the end-to-end wiring, including a copy-URL action and client-side PNG export.

Potentially Breaking Changes

• [deps] Update the minimum required Node version to 22 #88
• [deps] Raise the minimum required VS Code version to 1.101, needed for the stabilized MCP definition provider API; installing in earlier versions will fail #95
