Tracing (#344):
- Add 'json' feature to tracing-subscriber dependency
- Emit JSON log format when CI=true or RUST_LOG_FORMAT=json is set
(structured log ingestion in CI pipelines)
- Add tracing::debug! with tick_ms/budget_ms/over_budget fields on each
tick for performance profiling and tier system debugging prerequisite
Schedule dump (#346):
- Add --dump-schedule CLI flag that prints bevy_ecs schedule graph and exits
without requiring TCP bridge or world setup
- Add make debug-schedule target for CI artifact generation and diff-based
regression detection of unintended system reordering
