Prove the following Lean 4 theorem from ChapterCoreBoundsEsa.

BookProof.CoreBounds.coreExt_symmetricOn_inc [DecidableEq ι] {c : ι → ℝ} {H₀ : lpFiniteModes ι →ₗ[ℂ] L2I ι} {A : ℝ} (hA : CoreRelBound c H₀ A) (hsym : ∀ u v : lpFiniteModes ι, (inner ℂ (H₀ u) ((v : L2I ι)) : ℂ) = inner ℂ ((u : L2I ι)) (H₀ v)) : SymmetricOn (maxDom c) (coreExt hA)

Formalization note: Lean 4 identifier BookProof.CoreBounds.coreExt_symmetricOn_inc.

Replaces the unuploadable node BookProof_CoreBounds_coreExt_symmetricOn, whose statement name is already declared inside its published definition bundle; the _inc suffix publishes the same statement as its own node.
