024c0c1e0c Harden Newton-Raphson gamma bounds, improve v0.20.0 test coverage 
Add positive-gamma clamp in L1/L2/L3 Newton-Raphson iterations to
prevent divergence on extreme mass ratios. Add missing CREATE EXTENSION,
tighter L1/L2 precision checks (4 decimal places), lagrange_distance_oe
test with Ceres, L1-Earth-L2 ordering verification, and DE fallback
tests for planetary moon Lagrange functions.

dbc1f20a46 Add v0.20.0: Lagrange point SQL functions, DE variants, regression tests 
37 new SQL objects (188 → 225 total):
- Sun-planet L1-L5: heliocentric, observe, equatorial, distance (5 IMMUTABLE)
- Earth-Moon L1-L5: observe, equatorial via ELP2000-82B (2 IMMUTABLE)
- Planetary moon L1-L5: Galilean/Saturn/Uranus/Mars families (8 IMMUTABLE)
- Hill radius, zone radius, mass ratio, point name (5 IMMUTABLE)
- DE variants with VSOP87/ELP2000-82B fallback (17 STABLE)

All 31 regression tests pass. 210/210 standalone math tests pass.
