Debug Panel — File-Drop Workflow + Multi-File Picker (v1.53.0)

RingBufferObserver.Save() persists traces as BOM-free JSON. The VSIX watches **/reslava-*.json and opens the Debug panel automatically — no HTTP server, no blocking call.

Save() path rules:

Call	File written	VSIX picks up?
buf.Save()	reslava-traces.json in bin/	✅
buf.Save("my-run")	reslava-my-run.json in bin/	✅
buf.Save("/abs/path/out.json")	exact path (no prefix)	❌ (escape hatch)

Generated DebugProxy always saves to reslava-debug-{methodName}.json — one file per method, never collides with manual Save().

Multi-file picker — when multiple reslava-*.json files exist, the Debug panel header shows a file picker. Labels strip the reslava- prefix (traces.json, debug-Process.json, debug-Validate.json). Switch between traces without closing the panel.

Source badge — small badge in the panel header shows where data came from: ⏳ waiting → 📄 file · {dir} when file data arrives, 🌐 http when the HTTP endpoint responds first.
