Dispatch parallel agent tasks with capped concurrency

Dispatch parallel agent tasks within cost cap

Batched parallel work where cost/quota capping is required and partial-failure detection is needed.

• · [object Object]

• · [object Object]

Tasks array and cap > 0

Partial dispatch failure (cap too low); agent null returns filtered; results/raw mismatch

• · Capped concurrency (step = max(1, floor(cap)))
• · Attempted vs chunk_count distinction
• · Two return paths (results/raw)
• · Per-task labels
