/**
 * Calculate boring bar deflection using cantilever beam theory.
 *
 * @formula
 *   I = π × d⁴ / 64
 *   δ = F × L³ / (3 × E × I)
 *   L/D ratio determines stability recommendation
 *
 * @reference Beam deflection: standard cantilever theory (Oberg, E. et al. "Machinery's
 *   Handbook", 31st Ed.). The L/D < 4 / 4-6 / 6-10 material-selection bands are a general
 *   shop-practice rule of thumb, not a numeric table published by a single named source —
 *   Sandvik Coromant's own published overhang limits are structured differently (by dampened
 *   vs. non-dampened adapter, not by bar material) and run higher, up to 10-18×D for its damped
 *   product lines. Treat the bands here as a starting-point heuristic, not a cited standard.
 *
 * @param input - Boring bar deflection parameters
 * @returns BoringBarDeflectionResult with deflection, L/D ratio, and recommendation
