No more subcrate nesting — src/, agents/, schema/, defaults/, build.rs
all live at the workspace root. poc-daemon remains as the only workspace
member. Crate name (poc-memory) and all imports unchanged.

search.rs → query/engine.rs (algorithms, pipeline, seed matching)
query.rs → query/parser.rs (PEG query language, field resolution)
query/mod.rs re-exports for backwards compatibility.
crate::search still works (aliased to query::engine).
crate::query::run_query resolves to the parser's entry point.
No logic changes — pure file reorganization.
