Teknium 53db597201 simplify(compat): hermes_state — drop 81 re-exports + 3 registry aliases + 3 shims, repoint 45 callers + 60 test files
hermes_state.py: delete every '# noqa: F401 (re-exported...)' import block (hermes_state_common/errors/guard/
readpool/sessions/fts/dbfile/wal/repair/registry + agent.context_compressor _DB_PERSISTED_MARKER_KEY); keep
only the names hermes_state.py itself uses, without noqa.
hermes_state_registry.py: drop get_shared_session_db/release_shared_session_db/close_shared_session_dbs
aliases; every caller (gateway/, tools/, tui_gateway/, cron/, mcp_serve, run_agent, tests) now imports
acquire/release/close_all/release_or_close from hermes_state_registry.
hermes_state_titles.py: drop set_auto_title_if_empty shim (title_generator keeps its getattr fallback).
Re-remove shim-only names restored by 34abf954bd: latest_user_message_row_id (tests call
latest_message_row_id(key, role='user'); role-targeting assertions kept) and get_session_activity (tests
build the snapshot via agent.session_activity.build_activity_snapshot over db.get_session(sid)).
hermes_state_wal._log_once resolves its dedupe sets as module globals instead of via hermes_state;
hermes_state_repair helpers call module globals directly (tests patch hermes_state_repair.<name>).
Frozen updater surface untouched (update_cmd_maint imports only SessionDB from hermes_state).

"""The conftest WAL gate must agree with hermes_state, and must not import it.
``tests/conftest.py::_wal_is_usable`` duplicates the SQLite WAL-reset version
predicate instead of importing ``hermes_state``. That is deliberate: importing
``hermes_state`` during collection caches ``DEFAULT_DB_PATH`` from the real
``~/.hermes`` before the per-test ``HERMES_HOME`` redirect, which makes tests
read the developer's live production database.
Duplication needs a guard, so these tests pin the two implementations in
agreement across the documented upstream boundaries.
