feat(FN-3954): blocker staleness fanout and escalation for tasks

Browse Source 
Merges FN-3954: adds a blocker fanout system where task staleness automatically escalates to upstream blocking tasks, with a new `blocker-fanout` core module, dashboard hooks wiring that surfaces escalation status on the board and executor status bar, and a new settings toggle to disable escalation.
