The model-aware fixture foundation is now able to generate Rails-native metadata for ephemeral model tables, but the remaining ordinary test cases still rely on globally managed fixed schemas. That coupling makes test ownership and fixture cleanup less clear.

This migration moves each ordinary model-backed test case to an inline with_model schema owned by its Test::Unit class, including the integration, manifest, and serialization cases in the new test hierarchy. It keeps the intentional manual boundaries for raw SQL, autoload timing, alternate connection pools, schema errors, namespaced constants, subprocesses, and STI.

The legacy suite now covers both metadata-aware loading for ephemeral model tables and metadata-free loading for a conventional checked-in fixture. Shared fixed-schema support is removed after its final consumer migrates.

This is the dependent migration for #116.

Removing the shared fixed-schema support also removes the per-test reconnect to an in-memory SQLite database, which Rails main now reuses instead of replacing.

It also trues up the docs now that #116 has merged. The maintainer plan records #49, #72 (for tables with a primary key), #109, #119 and #129 as resolved, and notes the remaining keyless-table ordering gap. The README no longer advises against namespaced models.

Refs #124 (closed by #116)

Fixed in 07e4e53. The test now calls ActiveRecord::FixtureSet.reset_cache before loading, and asserts the returned fixture set belongs to the current MagicalCreature. Running the legacy-mode tests first in the same process reproduced the stale set without the reset; the test only passed because both ephemeral models get the same with_model table name within one process.
