EPIC - Continuous improvements for VS Code extensions (1H2025 iteration)

[tiagobento]

Prev: #1422

Q1

• VS Code Extensions should keep their Editors in sync even when files change externally #119
• DMN Editor: Include model doesn't work in a multi-workspace situation on VS Code #602
• Add support for multi-folder workspaces on VS Code for DMN, BPMN, PMML, and SWF extensions.
• Root-level dangling BPMN files are blinking for every change when opened as a Diagram on the BPMN VS Code extension.
• Entries in the Problems tab are not being cleaned up when the PMML Editor is closed. The Problems tab should only show issues for the open files. The SWF works because it is using a different mechanism.
• Integrate VS Code's built in Cut/Copy/Paste menus with operations on the Editors #217
