[Feature Request] Consolidate workflow progress visibility and add post-workflow hooks

Bug Description
Workflow (multi-agent orchestration) UX feedback:

1. Progress is fragmented across 3 surfaces (inline block, /workflows, statusline);

none gives a single stable "which workflow / which step / how much left" view.

1. The inline progress block (agent fan-out arrows, token up/down indicators) is

noisy and unclear to users, and disappears quickly — leaves no sense of progress.

1. No built-in "all steps listed + current highlighted" one-line view; users must

hack it via agents writing a status file + a custom statusline script.

1. Editing a workflow script then running it by name uses a stale cached version

(registry snapshotted at session start) — confusing, looks like edits didn't apply.

1. No workflow-specific hook (no WorkflowStop/PostWorkflow); post-run actions must

piggyback on PostToolUse with matcher "Workflow", which can't see which workflow
ran or its results.

Request: a clearer, consolidated, real-time workflow progress view, and a dedicated
post-workflow hook.
