feat: add syntax check priority in @test-fix-agent prompt

Enhancement:
- Added "CRITICAL: Syntax Check Priority" section in @test-fix-agent template
- Positioned before Session Paths for maximum visibility

Requirements:
- Run syntax checker (TypeScript tsc --noEmit, ESLint, etc.) BEFORE any work
- Verify zero syntax errors before proceeding
- Fix syntax errors immediately if found
- Syntax validation is MANDATORY gate - no exceptions

Scope:
- Applies to all task types (test-gen, test-fix, test-fix-iteration)
- Agent-level enforcement (not in orchestrator flow)

Rationale:
- Syntax errors must be fixed before functional testing
- Prevents cascading failures from basic syntax issues
- Reduces iteration waste on trivial syntax problems

+    - Verify zero syntax errors before proceeding
+    - If syntax errors found: Fix immediately before other work
