Summary
This improves the opencode provider error when it returns text that cannot be parsed as JSON. Instead of only saying the output was unparsable, the error now includes the text length, the opencode event kinds seen, and a short bounded preview so the failure is easier to debug without dumping the full provider output.
I also added regression tests for malformed output, whitespace-only output, and preview truncation.
Fixes #71
Testing
Ran formatting, lint, TypeScript checks, the focused provider tests, and the full test suite locally.
