Planning doc updates:
- Replace estimate table with actual measured values from DT sweep test
- Add 0.5s and 2.0s data points (69m and 228m respectively)
- Mark DT sweep tests as COMPLETED section
- Add analysis note about linear scaling with DT
New tests in test_maneuver_planning.cpp:
1. DT sweep: Hohmann transfer separation vs time step
- Runs full Hohmann transfer at DT = {0.1, 0.5, 1.0, 2.0, 5.0, 10.0}
- Verifies final separation matches expected ranges
- Confirms ecc < 0.01 for DT <= 1.0
2. DT sweep: quantization error is bounded by DT
- Tests 9 trigger offsets per DT value at DT = {1, 5, 10, 30}
- Verifies quantization error is always in [0, DT)
- Verifies execution time matches ceil-to-step-boundary
3. DT sweep: Hohmann arrival burn timing error
- Measures exact timing error at each DT
- Reports position error estimate (timing_error × velocity)
- Confirms timing error < DT
All 157 tests pass (240,742 assertions).
