fix(playground): gate tool-output JSON parse on size/streaming, toast clipboard errors

Address review feedback on the large-tool-results PR:

- `tryFormatAsJson` now bails on streaming (partial JSON would fail-parse
  on every chunk → O(n²) over the stream) and on payloads above
  `RAW_RENDER_THRESHOLD` (the parse + stringify is itself a freeze risk
  for the multi-MB GitHub-MCP shapes this PR was written for; the raw
  `<pre>` branch already handles these correctly).
- The Copy button now awaits `navigator.clipboard.writeText` in a
  `try/catch` and surfaces a sonner toast on success/failure, instead of
  letting the rejection escape as an unhandled promise.

Tests cover the streaming-bypass, the oversized-JSON-bypass, and the
clipboard-failure-toast paths.
