Tal.Yuan 6f6cb6ea88 refactor(routes): move history domain into routes/history/ subpackage (#5090)
Slice 2d of the route-domain reorganization (#4082/#4071, per
specs/architecture-runtime-inventory.md §6.3). Moves history_routes.py into
routes/history/, leaving a backward-compat sys.modules shim at the old path.
Pure file reorganization, no behavior change.

The shim uses sys.modules replacement (same pattern as the merged gallery
#4903, research #4975, and memory #5007 slices) so that `import
routes.history_routes`, `from routes.history_routes import X`,
`importlib.import_module(...)`, and the `import ... as history_routes` +
`monkeypatch.setattr(history_routes, ...)` pattern used by
test_history_compact_tool_calls.py / test_fork_session_metadata.py all
operate on the same module object the application uses.

The canonical module does NOT depend on the shim — routes/history/
history_routes.py imports only from core/, src/, and routes.session_routes
(a sibling route module whose old import path stays valid via its own shim
when session is migrated later).

Three source-introspection test sites repointed to the new canonical path:
- test_history_db_fallback_hidden.py
- test_history_order_by_timestamp_regression.py
- test_model_helper_owner_scope.py

Adds tests/test_history_routes_shim.py to pin the sys.modules shim contract
(legacy and canonical paths resolve to the same module object; monkeypatch
via legacy alias reaches the canonical module).

Verified: compileall clean; full suite 4351 passed, 3 skipped.

"""Regression test for the history route shim (slice 2d, #4082/#4071).
The backward-compat shim at ``routes/history_routes.py`` uses ``sys.modules``
replacement so the legacy import path and the canonical ``routes.history.*``
path resolve to the *same* module object. This is required because
``test_history_compact_tool_calls.py`` and ``test_fork_session_metadata.py``
do ``import routes.history_routes as history_routes`` followed by
``monkeypatch.setattr(history_routes, "_verify_session_owner", ...)`` — for
those patches to take effect at runtime, the legacy module object and the
canonical one must be identical. This test pins that contract.
