v1.0.0 — multi-DB ops console (PostgreSQL + MySQL)

First stable release. cli2ui becomes a multi-database ops console: a full MySQL engine lands alongside the mature PostgreSQL one, behind the same safety-first, local-only UI.

MySQL support (8.0+)

The same console over a MySQL connection: table/column browse, read-only + write query runner (the server enforces read-only via START TRANSACTION READ ONLY), filter builder, CSV import, streamed CSV/JSON export, EXPLAIN parsed into the shared plan tree (so snapshots & diff work), index + table + column DDL, database create/drop, activity (SHOW PROCESSLIST) with cancel/kill, locks (performance_schema.data_lock_waits), health (unused indexes / sizes), backup & restore (mysqldump/mysql), a settings editor (SET PERSIST), and replication status with an attach recipe.

Degrade, don't lie

Engine.supports() / UNSUPPORTED: features with no MySQL equivalent (vacuum/bloat, schemas separate from databases, the planner what-if lab, replication slots) show as "not applicable" rather than an empty card. A safety signal like "is anything blocked?" raises a clear message instead of degrading to a false negative.

Verified live against MySQL 8.0 (engine sweep + browser); full test suite green (179 tests).
