docs: Token Philosophy v1.1 + Design Specification restructured

- TOKEN_PHILOSOPHY.md:
  - Added Token Lifecycle (Draft → Experimental → Stable → Deprecated → Removed)
  - Added Design Review Gate (6 mandatory checks before new token)
  - Added deterministic principle: two AI agents must arrive at same token choice
  - Restructured into 8 sections with clear hierarchy

- LANDVEX_DESIGN_SPECIFICATION.md:
  - Restructured into 4 parts: GOVERNANCE → TOKENS → COMPONENTS → VALIDATION
  - Added part headers and updated table of contents
  - Aligned with Token Philosophy lifecycle and review gate

Rationale: Governance before values. Prevents uncontrolled token growth
and ensures AI-assisted design development is deterministic and traceable.
