…orm (closes #153 phase 1) (#193) * feat(quantum): Hubbard1D — Lieb-Wu Bethe ansatz half-filling closed form (closes #153 phase 1) New model Hubbard1D for the 1D Hubbard chain at half filling, exposing the Lieb-Wu (1968) closed-form integrals via QuadGK + SpecialFunctions: - E_0/N = -4 t^2 ∫_0^∞ J_0(ω) J_1(ω) / [ω (1 + exp(ωU/2t))] dω - Δ_c = (16 t^2 / U) ∫_1^∞ √(ω² - 1) / sinh(2π t ω / U) dω - Δ_s = 0 exactly (rigorous gapless spinons) Two new AbstractQuantity subtypes (ChargeGap, SpinGap) live in core/quantities.jl. Off-half-filling (μ ≠ U/2) raises DomainError — general filling and finite-T QTM are deferred to phase 2. 23 standalone test cases pin both the U/t = 4 reference values and the free-fermion (U → 0: E_0/N → -4t/π) and Heisenberg-AFM (U → ∞: E_0/N → -4 t² log2 / U, Δ_c → U - 4t) asymptotic limits. Implementation registry rows added (method=:bethe_ansatz, reliability=:high). Docs page docs/src/models/quantum/hubbard1d.md registered.
