Add orbit::specific_angular_momentum_from_elements(semi_major_axis, eccentricity), the conserved specific orbital angular momentum: h = sqrt(mu * a * (1 - e^2)) = sqrt(mu * p) (m^2/s) the angular momentum per unit mass of the two-body orbit (twice the areal velocity, Kepler's second law; mu = MU_EARTH). Equivalently sqrt(mu*p) with p the semi_latus_rectum_from_elements (#384); at the apsides h = r*v, and for a circle (e=0) it reduces to circular_angular_momentum sqrt(mu*a) (#348). Guard mirrors semi_latus_rectum_from_elements (a > 0, 0 <= e < 1). Analytic test specific_angular_momentum_from_elements_is_sqrt_mu_p: (a) worked a=7e6, e=0.1 -> h = sqrt(mu*6.93e6); (b) cross-check threading semi_latus_rectum_from_elements (#384): h^2 = mu*p across three (a,e); (c) circular cross-check threading circular_angular_momentum (#348): h(a,0) = sqrt(mu*a); (d) periapsis cross-check threading orbital_speed: h = r_p*v_p; (e) Err guards for a<=0, e>=1, non-finite. Free fn in orbit.rs (reached via valenx_astro::orbit::), no lib.rs change. valenx-astro 221 lib tests (was 220), cargo clippy --all-targets -D warnings clean.

Add orbit::apoapsis_radius_from_elements(a, e) = a*(1+e) and periapsis_radius_from_elements(a, e) = a*(1-e), the farthest and closest orbital radii (m) from the conic elements. Together they are the forward (a, e) -> apsides direction, completing the apsides<->elements bijection: eccentricity_from_apsides (#372) and semi_major_axis_from_apsides (#378) go apsides -> (e, a); these go (a, e) -> apsides. Guard mirrors semi_latus_rectum_from_elements (a > 0, 0 <= e < 1). Analytic test apsis_radius_from_elements_completes_the_apsides_bijection: (a) worked a=7e6, e=0.1 -> r_a=7.7e6, r_p=6.3e6; (b) double round-trip threading #372 + #378 (non-tautological): the computed apsides recover BOTH e and a; (c) threads semi_latus_rectum_from_elements (#384): the harmonic mean of the apsides is the semi-latus rectum p = a(1-e^2); (d) ordering r_p <= a <= r_a and r_a + r_p = 2a; (e) circular: e=0 -> both apsides collapse to a; (f) Err guards for a<=0, e>=1, non-finite (both fns). Free fns in orbit.rs (reached via valenx_astro::orbit::), no lib.rs change. valenx-astro 222 lib tests (was 221), cargo clippy --all-targets -D warnings clean.
