Read workflow-status telemetry from CLI transcript files

Dynamic ultracode workflows run as a detached background task with their
own transcript dir, so their subagent events never flow through the main
-p stream. The previous parent_tool_use_id tap therefore captured nothing
for real workflows and the status stayed "none" the whole run.

Replace the tap with a file-based reader:
- TapWorkflowLaunch parses the "Transcript dir:" line from the Workflow
  tool_result and registers the run.
- WorkflowProgressTracker becomes a per-session registry of transcript
  paths (no longer a stream accumulator).
- WorkflowTelemetryReader reads journal.jsonl for live counts (running)
  and <runId>.json for rich per-agent telemetry (completed); FinalizeChain
  persists the rich JSON into chains.workflow_info.
- Modal renders phases + a per-agent list (label/phase/state/tokens/
  tool-calls/duration) instead of the obsolete tool breakdown.

Sync ARCHITECTURE.md, ARCHITECTURE_QUICK.md and README.md to the new
mechanism.
