refactor: extract bridge state layer to muse.core.bridge.state (issue #14 Phase 1)

Move BridgeState TypedDicts, read_bridge_state, write_bridge_state, and _dict_to_toml out of the 3138-line bridge.py god object and into a focused muse.core.bridge.state module. bridge.py now imports from there.

Also create muse/core/bridge/__init__.py and muse/core/bridge/state.py. All 152 bridge-related tests remain green.
