fix(testdata): Update SQLite tests for real database analyzer

The SQLite database analyzer now validates queries against real SQLite,
revealing several issues in test files:

- builtins: Remove sqlite_offset (not available in standard SQLite)
- ddl_create_trigger: Add missing tables referenced by trigger
- insert_select_invalid: Separate schema from query, update error message
- invalid_group_by_reference: Separate schema from query, update error message
- invalid_table_alias: Fix INT to INTEGER, separate schema, update error
- join_left_same_table: Fix authors.parent_id to a.parent_id (use alias)
- limit: Remove UPDATE/DELETE LIMIT (requires special compile option)
- quoted_names_complex: Fix UPDATE referencing renamed table
- select_exists: Change INT to INTEGER for AUTOINCREMENT
- select_not_exists: Fix whitespace, detect parameter
- sqlc_embed: Use :memory: for ATTACH, fix u.users.id to u.id

Tests with different error messages in base vs managed-db contexts now
have exec.json files limiting them to managed-db context only.
