Conversation
NEW documentation/sql/joins.md — the in-repo Markdown twin of the canonical website page (SOFTNETWORK-APP/softclient4es-web#11): two-superpowers lead, the JOIN ladder, the three rows (same-cluster passthrough / cross-cluster conveyor / multi-source coordinator) with worked SQL transcribed verbatim from the JDBC + federation integration tests, all three diagrams as fenced ASCII, the qualitative performance section, and the quota-as-meter licensing section. Add the page to the SQL doc index (README.md) and reconcile the stale JOIN-limitation copy in dql_statements.md (the top "What is supported" list and the Limitations "joins only via Materialized Views" bullet) to point at the new page. Cross-links to not-yet-merged targets are marked pending (Epic-17-close launch gate). Dual-docs parity verified against the canonical MDX.
