v0.2.0

MySQL & MariaDB query builder

Adds a new MySQL\Q facade — a single fluent, immutable builder covering both
MySQL 8.4 and MariaDB 11.x. Rendering is fully determined by construction, not a
dialect flag.

Highlights

• Full SELECT family: joins, CTEs (WITH), window functions, grouping, ordering,
  and the JSON selection shape.
• INSERT / UPDATE / DELETE / REPLACE, including ON DUPLICATE KEY UPDATE.
• MySQL-native expression surface: <=>, the ->/->> JSON operators, and the
  JSON function set (JSON_TABLE, JSON_CONTAINS, …).
• Engine-divergent constructs are validated on an opt-in pass —
  Q::build($q)->withValidateTarget(Target::mysql() | Target::mariaDb()) reports
  what the target can't express (version-gated where relevant, e.g. MariaDB-only
  RETURNING).

Also — additional PostgreSQL builder tests and coverage.

Full changelog: v0.1.0...v0.2.0

v0.1.0

First release of the query object builder for fully typed, complex SQL queries.

In this version we focused on a port from https://github.com/networkteam/qrb and implement the PostgreSQL builder and dialect.

Important: Expect the API to change slightly until we settle the PHP shape.
