Add the fundamental Monster-Coxeter relation:
dim(M₁) = (b₃ - h(G₂)) × (b₃ - h(E₇)) × (b₃ - h(E₈))
= 71 × 59 × 47 = 196883

This expresses the Monster group's smallest faithful representation dimension purely in terms of the third Betti number b₃=77 and Coxeter numbers of exceptional Lie algebras.

Changes:

  • Core.lean: Add Coxeter numbers h_G2=6, h_E6=12, h_E7=18, h_E8=30
  • MonsterCoxeter.lean: New module with main theorem and structural relations
  • JInvariant.lean: Add j-coefficient ratio observations (c₂/c₁ ≈ 109)
  • Moonshine.lean: Import and integrate MonsterCoxeter module

The formula is exact (no remainder), intrinsic (fundamental invariants), and connects Monstrous Moonshine to exceptional Lie theory via G₂-geometry.

Add the fundamental Monster-Coxeter relation:

          = 71 × 59 × 47 = 196883

This expresses the Monster group's smallest faithful representation
dimension purely in terms of the third Betti number b₃=77 and
Coxeter numbers of exceptional Lie algebras.

Changes:
- Core.lean: Add Coxeter numbers h_G2=6, h_E6=12, h_E7=18, h_E8=30
- MonsterCoxeter.lean: New module with main theorem and structural relations
- JInvariant.lean: Add j-coefficient ratio observations (c₂/c₁ ≈ 109)
- Moonshine.lean: Import and integrate MonsterCoxeter module

The formula is exact (no remainder), intrinsic (fundamental invariants),
and connects Monstrous Moonshine to exceptional Lie theory via G₂-geometry.
- MonsterCoxeter.lean: move imports before docstring (Lean 4 requirement)
- JInvariant.lean: fix j_coeff_2_remainder calculation
  (109 × 196884 = 21460356, remainder = 33404, not 21296876)
- CHANGELOG.md: Add v3.3.11 release notes (Monster-Coxeter formula)
- README.md: Bump version to 3.3.11, add MonsterCoxeter.lean
- CLAUDE.md: Add tip #46 (import order before docstrings)
- docs/USAGE.md: Add v3.3.11 section with Lean examples
- gift_core/_version.py: Bump to 3.3.11

New features:
- dim(M₁) = (b₃ - h(G₂)) × (b₃ - h(E₇)) × (b₃ - h(E₈)) = 196883
- Coxeter numbers h_G2, h_E6, h_E7, h_E8 in Core.lean
- j-coefficient ratio observations (c₂/c₁ ≈ 109, c₃/c₂ ≈ 40)
