refactor(semantics): migrate TIER system to adaptive COMPLEXITY 1-5 scale

- Replaced rigid TIERs with continuous COMPLEXITY 1-5 scale in semantics.md
- Updated generate_semantic_map.py to parse and score based on Complexity
- Added backward compatibility mapping for legacy TIERs
- Migrated all .ai/shots examples to use @COMPLEXITY and updated relation syntax
- Added trivial_utility.py shot to demonstrate implicit Complexity 1 token savings
