Align artifacts with canonical URT v5.1 specification

Fixes inconsistencies discovered during audit against urt-taxonomy/:

- urt_profile ENUM: Add 'lite' and 'core' profiles (was missing)
- USN format: Use canonical regex from spec (was non-compliant)
- USN valence encoding: Add V0 (0) and V± (±) support
- USN grammar: Add Lite (URT:L:) and Core (URT:C:) formats
- Dimension codes: Fix temporal (TC/TR/TH/TF), evidence (ES/EI/EC),
  comparative (CR-N/CR-B/CR-W/CR-S) in decisions doc
- LLM contract: Full USN regex validation pattern
