Release note

Catches the MemGQL docs up to three merged product PRs:

  • RETURN p / RETURN r now return structured Bolt Nodes & Relationships on every SQL backend (PostgreSQL, MySQL, DuckDB, ClickHouse, Iceberg, Pinot, Oracle) — a map projection is no longer required.
  • Connection-less liveness queries (RETURN 1, RETURN 1 + 2 AS x) now work with no backend configured.
  • PostgreSQL NUMERIC columns deserialize correctly, ORDER BY can reference a RETURN alias in cross-backend queries, and delimited (quoted) identifiers parse.

Adds a v0.7.0 changelog section and new feature-matrix rows, and removes the now-obsolete "RETURN n returns column values" limitation from the reference and the postgres/mysql/duckdb connector pages.

…R BY alias

Catch the memgql docs up to PRs #24, #29, #30:
- changelog: new v0.7.0 section (typed RETURN p / RETURN r, connection-less
  RETURN 1 liveness, ORDER BY by RETURN alias, delimited identifiers, Postgres
  NUMERIC fix)
- reference: add whole-node/whole-relationship + liveness matrix rows; drop the
  now-false 'RETURN n returns column values' limitation
- connect/{postgres,mysql,duckdb}: add whole-node/whole-relationship matrix row;
  drop the stale RETURN n limitation
… PG/MySQL/DuckDB

apply_descriptors is wired into all seven SQL connectors (incl. ClickHouse,
Iceberg, Pinot, Oracle); match the PR title's 'on every SQL backend'.
…berg, Pinot pages

Typed projections (PR #29) work on every SQL connector; surface it in the
feature table of the narrower-verified connector pages too.
