fix(task): remove max_turns parameter from task tool interface (#2783)

* fix(task): remove max_turns parameter from task tool interface

Subagents should always use their configured max_turns value. Exposing
this parameter allowed callers to override the admin-configured limit,
which is undesirable. The value is now exclusively driven by subagent
config (per-agent overrides and global defaults in config.yaml).
