test(M00): add renderer coordinate calibration

Work-Package: M00-QAR-COORD-CALIBRATION-001
Agent: sindo-main-codex
Tests: coordinate probe, M00 dry-run, coordination and documentation gates
Fidelity: five build 12340 camera points round-trip within 0.000015 units

 - Integration/E2E: Eastern Kingdoms/Kalimdor streaming scenes and seven cold/warm checkpoints.
 - Fidelity evidence: пять локальных build 12340 reference JPG откалибровали terrain/ADT/M2/WMO/liquid viewpoints; automated paired-image metrics exist, но synthetic animation/dusk и полный human approval ещё не закрыты.
 - Performance budgets: M00 report records cold/warm p95 and max hitch; no final acceptance threshold yet.
