fix: Correct YAML syntax in harmony-check workflow with proper heredoc indentation

Fixed critical YAML syntax error in harmony-check.yml caused by incorrect
heredoc indentation:

**Problem:**
- Python heredoc content and terminators were unindented (column 0)
- This broke YAML's literal block (run: |) parsing
- YAML parser failed with "could not find expected ':'" error
- GitHub Actions workflows would not run

**Root Cause:**
In YAML literal blocks (|), all lines must maintain consistent base indentation.
The heredoc pattern `python3 << 'EOF'` with unindented Python code and EOF
terminator violated this requirement.

**Solution:**
1. Changed `<< 'PYTHON_SCRIPT'` to `<<'PYTHON_SCRIPT'` (no space)
2. Indented all Python code to match surrounding bash code (10 spaces)
3. Indented PYTHON_SCRIPT terminators to match (10 spaces)

This preserves YAML structure while bash correctly strips the indentation
when processing the heredoc.

**Files Fixed:**
- Job 2 (harmony-json-report), Step 3: Generate JSON Harmony Report
- Job 2 (harmony-json-report), Step 5: Display Top 5 Disharmonious Functions

**Testing:**
- ✅ YAML validates with Python yaml.safe_load()
- ✅ Extracted bash script executes correctly
- ✅ JSON parsing works as expected
- ✅ All heredoc syntax functional

This resolves the CI workflow failures reported by the user.
