Corrects the Status Board (PLAN-04 24/26, not 0), and adds a Parallelization Map to
00-MASTER-TRACKER plus a per-plan Parallelization block to PLAN-04/05/06/07/08. Derives
ready sets from the live .tasks.json blockedBy graphs and the Files metadata, identifies
the initiative-wide serialization mutexes (ManagementActor.cs single-writer, EF migration
snapshot, Host/Program.cs, ArtifactDeploymentService.cs, SiteStorageService.cs,
NotificationOutboxActor.cs, AlarmSummary.razor), and recommends the safe concurrent
subagent lanes per plan. Flags PLAN-07 T33 as a dedupe-skip (CLI.Tests already in slnx).
