docs: update README-changes.md with v1.3.0 complexity routing feature

Updated documentation to include:
- Complexity-based routing overview
- MICRO/STANDARD/COMPLEX classification algorithm
- Risk keyword scoring system
- Token savings (50-70% for micro stories, 90% for early bailouts)
- Integration with super-dev-pipeline and batch-super-dev
- Latest commit information (9bdf4894)

+**Complexity Scoring Algorithm:**
+```
+complexity_score = task_count + (high_risk_keywords × 5) + (medium_risk_keywords × 2)
+
+MICRO:    task_count ≤ 3 AND score ≤ 5 AND file_count ≤ 5 AND no HIGH risk keywords
+COMPLEX:  task_count ≥ 16 OR score ≥ 20 OR has HIGH risk keywords (auth, security, payment, etc.)
+STANDARD: everything else
+```
+
+**Risk Keywords:**
+- **HIGH** (5 points): auth, security, payment, encryption, migration, database, schema
+- **MEDIUM** (2 points): api, integration, external, third-party, cache
+- **LOW** (0 points): ui, style, config, docs, test
