fix(packaging): add missing hermes_state_* modules to py-modules list (#74287)

[RelaxJonh]

Summary

hermes_state.py imports four sibling top-level modules that are not listed in [tool.setuptools] py-modules, so they are never packaged in wheel/sdist builds. Any install built from pyproject.toml (pip/uv wheel, nix, distro packaging) silently disables the SQLite session store because the modules are missing from the distribution.

Git installs are unaffected since they run from the repo tree where the files are present.

Root Cause

hermes_state.py imports:

• hermes_state_common (line 46, re-exported for back-compat)
• hermes_state_portability (line 70, SessionPortabilityMixin)
• hermes_state_schema (line 71, SessionSchemaMixin)
• hermes_state_search (line 72, SessionSearchMixin)

But pyproject.toml line 348 only lists hermes_state — the four dependencies are absent.

Fix

Add the four missing modules to the py-modules list in pyproject.toml.

Testing

• All 4 existing packaging tests pass (tests/test_packaging_build_guard.py)
• Verified the modules exist in the repo root
• Verified the imports in hermes_state.py match the added module names

Fixes #74287

Duplicate of #74393: both add the same four missing hermes_state_* py-modules. #74393 is the canonical patch because it also covers build and wheel regression checks.
