Fix scenario tests: paths, verifications, streaming, and parallel execution

- Fix relative paths in TS package.json (43 files) and Python requirements.txt (33 files)
- Add RollForward to C# csproj files for .NET 8/10 compat
- Remove soft-pass fallbacks in verify.sh — tests now hard-fail on missing patterns
- Fix Go permissions bug (req.Kind → req.ToolName) and add ToolName to SDK type
- Fix Python/Go availableTools: empty list was omitted instead of sent as []
- Fix streaming event names (assistant.message.chunk → assistant.message_delta)
- Fix TS streaming subscription (session.on('event') → typed subscription)
- Fix Python streaming enum comparison (event.type.value)
- Add permission handlers to Go skills scenario
- Switch scenarios to claude-haiku-4.5 for faster execution
- Parallelize verify.sh with live progress bar and per-SDK status icons
- Fix parallel pip install race with pre-install and import check
- Remove go.sum files from tracking
- Remove hardcoded OAuth client ID from C# gh-app scenario
