Adds a SqliteDialect alongside PostgresDialect, gated by mutually exclusive postgres (default) / sqlite Cargo features, plus a feature-selected ActiveDatabase type alias used throughout the public Georm/Defaultable traits. Basic CRUD and Defaultable are fully covered by a new SQLite test suite (tests/sqlite/*) running against a real SQLite database, alongside split migrations/sqlite/*. Two real dialect differences surfaced beyond placeholder syntax: - SQLite's INTEGER columns type-infer as i64 in sqlx's compile-time query macros (unlike Postgres SERIAL -> i32), so the SQLite test models use i64 for integer PK/FK fields. - sqlx's SQLite query macros need bind arguments bound to a place rather than passed as an inline expression (fixed once, centrally, in SqlDialect::generate_relation_lookup). Composite-key entities with chrono::DateTime columns (tests/composite_key.rs) are not yet ported to SQLite: SQLite has no TIMESTAMPTZ equivalent, so sqlx infers TEXT date/time columns as String rather than DateTime<Utc> unless the query explicitly overrides the column type. That needs per-field type overrides threaded through the generated queries, left as follow-up. CI now matrixes over both backends; formatting/audit only run once since they don't vary by backend. examples/postgres/* stays out of --no-default-features builds by scoping sqlite lint/test just recipes to `-p georm` (it depends on georm's default postgres feature via Cargo feature unification, so building it under --features sqlite at the workspace level double-activates both dialects).

// UserRole (composite key, chrono::DateTime<Utc> column) is deliberately not
|
|
// ported here yet: SQLite's compile-time query macros infer TEXT columns as
|
|
// `String`, not `chrono::DateTime<Utc>` — unlike Postgres's TIMESTAMPTZ, which
|
|
// maps directly. Fixing this needs per-column `query_as!` type overrides
|
|
// (`"assigned_at as \"assigned_at: DateTime<Utc>\""`) threaded through the
|
|
// dialect's generated queries, which is follow-up work, not part of this
|
|
// first SQLite slice. See tests/sqlite/composite_key.rs (not yet added).
