Switch run generator command to use active target-set and extend diagnostics

[brondani]

Fixes

• [csolution] csolution run test.csolution.yml -g myGenerator reports board not found if a none selected cproject.yml lists a missing pack cmsis-toolbox#619
• Depends on [projmgr] Global Generator: update context selection, defer partial processing failures devtools#2504

Changes

The Run Generator command previously passed a context string to csolution run via -c. This change passes the active <target-type>[@<target-set>] with the -a flag instead. This aligns with the csolution CLI's preferred way of addressing context selection by active target.

In addition, generator run output is now routed through the diagnostic pipeline so that any csolution error/ warning lines appear in the Problems panel — consistent with convert and cbuild output.

• Generator Command Enhancement
  • Added activeTarget?: string to RunGeneratorRequest interface
  • Modified handler to accept activeTarget parameter
  • Captures output lines during execution for diagnostic processing
  • New: Fires generator completion event
• Diagnostic Resolution
  • Added optional getActiveTargetSetName constructor parameter
  • Enables dependency injection for testability while maintaining zero-dependency defaults
• Event Hub Enhancement
  • Added new interface method, event and emitter for generator run completion
  • Enables generator diagnostics to be processed identically to convert/cbuild diagnostics
• Solution Outline Tree Integration
  • Enables context menu commands to use current active target set

Pull request overview

This PR updates the VS Code extension’s Run Generator workflow to prefer the CMSIS Toolbox csolution run active target selection (-a <target-type>[@<target-set>]) instead of passing a build context string (-c), and routes generator output through the existing diagnostics pipeline so generator-related errors/warnings surface in the Problems panel like convert/cbuild.

Changes:

• Switch generator invocation to accept and forward activeTarget (and keep legacy context support where still provided).
• Add a generator-run completion event to the solution event hub and consume it in SolutionProblems to produce diagnostics from generator output.
• Propagate activeTarget into solution-outline “component-gen” nodes and update reference dumps/tests accordingly.
