🤖 I have created a release beep boop

1.0.0 (2026-07-20)

⚠ BREAKING CHANGES

• drop utils (quasi_random -> photomancy)
• observatory: drop zodiacal photometry; geometry only (zodi -> skyscapes)
• remove system (Planets/Star/System) and exosims integration; owners: exosims-plugins, skyscapes
• promote orbit to orbix.orbit, solar_system to observatory; top-level exports
• orbit: recompute AB per call, arctan2 phase angle, shape-validated elements
• remove broken predict.pdet, discrete_e factory, dead bilinear path

Features

• equations: elliptic multi-rev Lambert boundary-value solver (24dfe46)

Bug Fixes

• ci: fix python floor mismatch with hwoutils and drop stale test job (a181ade)
• ci: modernize test workflow and fix python floor mismatch with hwoutils (4186f0c)
• equations: NaN-safe gradients in state_vector_to_keplerian at circular/equatorial (32161b6)
• kepler: append top e row to bilinear grids; ValueError on E=trig=False (0126374)
• kepler: correct cosE reconstruction at bit-exact M=pi (92d3395)
• kepler: hermite 2pi seam unwrap, nearest-node lookups, honest linear-grid docs (b7d6f21)
• kepler: wrap M mod 2pi in all shortcut solvers; document e domain (0b2ede2)
• orbit: recompute AB per call, arctan2 phase angle, shape-validated elements (c2a268f)

Code Refactoring

• drop utils (quasi_random -> photomancy) (86bd9e2)
• observatory: drop zodiacal photometry; geometry only (zodi -> skyscapes) (3aa845d)
• promote orbit to orbix.orbit, solar_system to observatory; top-level exports (74f1c0c)
• remove broken predict.pdet, discrete_e factory, dead bilinear path (3a9ac12)
