refactor(examples): Consolidate tier examples into unified folder

Reorganized all application tier examples into a single `tiers/` folder
with consistent prefixed naming:

Tier 1 (Practical):
- t1_anomaly_detection: Infrastructure anomaly detection
- t1_edge_autonomy: Drone/vehicle autonomy
- t1_medical_wearable: Medical monitoring

Tier 2 (Transformative):
- t2_self_optimizing: Self-stabilizing software
- t2_swarm_intelligence: Distributed IoT coordination
- t2_adaptive_simulation: Digital twins

Tier 3 (Exotic):
- t3_self_awareness: Machine self-sensing
- t3_synthetic_nervous: Environment-as-organism
- t3_bio_machine: Prosthetics integration

Benefits:
- Easier navigation with alphabetical tier grouping
- Consistent naming convention (t1_, t2_, t3_ prefixes)
- Single folder reduces directory clutter
- Updated Cargo.toml and README.md to match
