IcyDB Core

Runtime engine for IcyDB.

icydb-core contains execution, planning, storage-facing runtime logic, and observability plumbing used by the public icydb crate.

Most applications should depend on icydb directly. Use icydb-core only when you explicitly need internal runtime surfaces.

Current execution baseline in 0.18.x includes stream-native composite execution (Union/Intersection) and guarded pagination scan budgeting for safe plan shapes.
