claude's Task tool spawns subagents whose progress lands as
stream-json events with subtype=task_started or
task_notification — previously fell through to the .sys
catch-all and rendered as a raw json dump that wrapped per
char in the live pane.
now matched by subtype before the catch-all:
- task_started → cyan tool-use row, ⌁ glyph, first 8 chars of
task_id, description, and optional [task_type]
- task_notification → row styled by status: completed →
turn-end-ok (green ✓), failed → turn-end-fail (red ✗),
other → tool-result (muted ◌). output_file rendered inline
if present so the operator can trace where the body landed.
matching on `v.subtype` rather than a particular `v.type` so
the renderer survives claude wrapping these under different
top-level type fields across versions.
