 - [x] 3) lsp e2e chat/document: chat test now uses multi-line reply and validates insertion contains both lines; document resolve uses multi-line docblock.
 - [x] 4) lsp completion: manual-invoke test now uses a multi-line realistic function signature with body; still passes and exercises formatting.
 - [x] 5) llm providers: added OpenAI success + SSE stream and Copilot token+chat + Codex SSE tests; coverage ≥80%. Expanded with multi-choice and error-body cases.

+- [x] 6) General: introduced shared fixtures (internal/testutil) and added table-driven tests for code fences, inline spans, label selection, prefix stripping, and instruction markers.
 - [x]    Added table-driven tests for instruction marker extraction and prefix stripping.
