Turso is a distributed SQLite database built on libSQL, offering HTTP-based
connectivity with auth token authentication. This change adds full support:
- New DatabaseType::Turso and PoolKind::Turso variants
- TursoClient driver using libSQL HTTP pipeline API (/v2/pipeline)
- Bearer token auth via password or url_params (auth_token=)
- Multi-statement batch pipeline for transactional integrity
- Standalone BEGIN/COMMIT/ROLLBACK treated as no-ops (pipeline is auto-commit)
- Full metadata support: tables, columns, indexes, foreign keys, triggers, DDL
- Frontend: connection form, SQL completion (SQLite syntax), capability sets
- Built-in databases (SQLite/Turso/DuckDB/RQLite/Access) placed first in selector
- Unit tests (15) + integration tests against live libsql-server (12)
- Single connection pool, skips TCP probe
Closes#948
When changing a column's data type in the table structure editor, the
length parameter now updates to a sensible default for the new type
(e.g. int→11, tinyint→4) instead of preserving the old value.
- Separate data type input into type dropdown (SearchableSelect with allowCustom)
and length input, Navicat-style
- Add comprehensive DATA_TYPE_OPTIONS for all 6 database engines, validated
against official docs
- Add Shiki SQL syntax highlighting to the SQL preview panel
- Add i18n keys for new UI elements (typePlaceholder, length, noMatchingType)
