algeon-query-runtime
algeon-query-runtime owns the attempt lifecycle, admission to a GPU, the
per-device memory ledger and its immutable grants, resident caches, and the
observation snapshot that reports and metrics read. It depends on
algeon-query-planning and algeon-cudf, and algeon-query-engine and
algeon-datafusion build on it. Applications depend on algeon-datafusion,
which re-exports the runtime types they need.
Memory and query lifetime and runtimes and threads document the contracts.
