**Issue**: 30 CI tests failing with "incomplete input" database error
- tests/unit/mcp/get-node-essentials-examples.test.ts (16 tests)
- tests/unit/mcp/search-nodes-examples.test.ts (14 tests)
**Root Cause**:
Both `src/mcp/server.ts` and `tests/integration/database/test-utils.ts`
used naive `schema.split(';')` to parse SQL statements. This breaks
trigger definitions containing semicolons inside BEGIN...END blocks:
```sql
CREATE TRIGGER nodes_fts_insert AFTER INSERT ON nodes
BEGIN
INSERT INTO nodes_fts(...) VALUES (...); -- ← semicolon inside block
END;
```
Splitting by ';' created incomplete statements, causing SQLite parse errors.
**Fix**:
- Added `parseSQLStatements()` method to both files
- Tracks `inBlock` state when entering BEGIN...END blocks
- Only splits on ';' when NOT inside a block
- Skips SQL comments and empty lines
- Preserves complete trigger definitions
**Documentation**:
Added clarifying comments to explain FTS5 search architecture:
- `NodeRepository.searchNodes()`: Legacy LIKE-based search for direct repository usage
- `MCPServer.searchNodes()`: Production FTS5 search used by ALL MCP tools
This addresses confusion from code review where FTS5 appeared unused.
In reality, FTS5 IS used via MCPServer.searchNodes() (lines 1189-1203).
**Verification**:
✅ get-node-essentials-examples.test.ts: 16 tests passed
✅ search-nodes-examples.test.ts: 14 tests passed
✅ CI database validation: 25 tests passed
✅ Build successful with no TypeScript errors

Major improvements based on comprehensive test suite review:
Test Fixes:
- Fix all 78 failing tests across logger, MSW, and validator tests
- Fix console spy management in logger tests with proper DEBUG env handling
- Fix MSW test environment restoration in session-management.test.ts
- Fix workflow validator tests by adding proper node connections
