/**
 * Tests for Bug 3: lspGetSemantics truncation removed + symbolName validation.
 *
 * 1. type='definition' without symbolName should fail schema validation.
 * 2. contentPreview must return the full content string (no truncation at
 *    1200 chars).
 * 3. The oneLine compact formatter still truncates to 180 chars for row
 *    display, but appends a guidance note rather than silently cutting.
