Closes the second half of the May 15 audit's workspace partial entry. Thalamus mode-broadcast closed the first half (org_state coupling); this closes the bandwidth-limit half. Biology: Dehaene-Changeux global neuronal workspace has a hard ~4-chunk ignition bandwidth. Phase 1 is bookkeeping + shadow enforcement. Phase 2 wires the limit into workspace_ingest. Phase 3 lets ARAS modulate the bandwidth. - Migration 072: workspace_bandwidth_state (single row, defaults: limit=4, epoch=60s, mode=shadow) + workspace_bandwidth_epochs (historical log of completed epochs with saturation tracking). - mcp_tools_workspace_bandwidth: 4 tools (status, set, admit, epochs_history). admit returns admitted/rejected/saturated; in shadow mode all admits go through but saturated=True is logged; in enforce mode admits over the limit are rejected. - Auto-rotation: status + admit check epoch expiry and roll the live counters into the historical table. - 9 tests covering defaults, status, admit, saturation, enforce rejection, set validation, rotation timing, history filters.
