Export the keyset! macro for peer repository crates

[martsokha]

keyset! (the shared keyset-pagination helper for cursor listings) was pub(crate), usable only within nvisy-postgres. The cloud server's nvisy-cloud-postgres crate has its own repository layer and needs the same helper for its own cursor-paginated queries, so this makes it #[macro_export] — callable as nvisy_postgres::keyset!.

Why this is a clean export

• The macro already references Direction by its absolute $crate::types::Direction path (publicly reachable), so a peer crate needs no extra import for it.
• It expands only to Diesel query-builder calls, so the sole requirement at a call site is diesel::prelude::* in scope.
• nvisy-cloud-postgres is a peer of nvisy-postgres (another repository/query layer), not an upper layer, so exporting query-layer infrastructure to it doesn't cross the handler → domain → query boundary.

Compatibility

The existing pub(crate) use re-export chain (cursor → pagination → types) is kept, so in-crate call sites (use crate::types::keyset;) are unchanged.

Verification

cargo check/clippy --all-targets -D warnings/+nightly fmt --check/RUSTDOCFLAGS=-D warnings cargo doc clean; nvisy-postgres cursor tests pass. One-line change (visibility only), no behavior change.
