The task tool runs an entire sub-agent that carries its own bounds (maxTurns, no-progress, thrash, opt-in deadlineMs). The uniform per-tool wall-clock budget (default 660s) aborted healthy workers past 11 minutes through the cancel path. resolveToolExecutionTimeoutMs now returns undefined for task calls, and the opt-in sub-agent deadline is no longer clamped under an outer watchdog that no longer applies.

The
tasktool ran an entire sub-agent under the same per-tool wall-clock watchdog as every other tool (default 660s), so workers needing more than 11 minutes were aborted mid-run and reported as cancelled.resolveToolExecutionTimeoutMsnow returnsundefinedfortaskcalls, leaving the sub-agent's own bounds (maxTurns, no-progress, thrash, opt-indeadlineMs) as the operative limits. The opt-in deadline is no longer clamped under an outer watchdog that no longer applies, and a regression test covers a slow-but-progressing task run outlasting the generic budget.Fixes CL-6773
