fix: Cannot read properties of undefined (reading 'format')

Error: Cannot read properties of undefined (reading 'format')
Source:
Location: Line 0, Col 0

Fix summary

In formatNode, node.metadata!.format used a TypeScript non-null assertion that suppressed compile-time warnings, but metadata is genuinely undefined at runtime for non-completed tasks (set explicitly in collectMetrics) and for the root aggregate node (which has no metadata property), causing a TypeError when any such node is visited during recursive tree formatting.

Replaced the unsafe non-null assertion node.metadata!.format with optional chaining and a nullish fallback: node.metadata?.format ?? "pending" in the formatNode function. This ensures that when metadata is undefined — for incomplete tasks or the synthetic root node — the format label safely defaults to "pending" instead of throwing a TypeError. No other code was changed.
