Adds a new "user-reported" mode alongside the existing automated
diagnostics mode. Users can now choose to:
1. Run automated diagnostics (existing behavior)
2. Report an issue they experienced while using any plugin command
User-reported mode:
- Step 0: Mode selection via AskUserQuestion
- Step 0.1: Structured feedback gathering
- Which plugin/command was affected
- What the user was trying to do
- What went wrong (error, missing feature, unexpected behavior, docs)
- Expected vs actual behavior
- Any workarounds found
- Step 5.1: Smart label generation based on problem type
- Step 6.1: User-friendly issue template with investigation hints
This allows capturing UX issues, missing features, and documentation
problems that wouldn't be caught by automated MCP tool tests.
Fixes#139
