fix(tools): expose maxTurns on the subagent tool params (v0.9.3) - #13

Conversation
The subagent tool was hard-capped at 20 turns (DEFAULT_MAX_TURNS) with no way for the caller to raise it. Complex tasks (read a large file + plan + implement + test + commit) routinely hit the budget mid-task — Tasks 5/6/10 in the SPEC-6-1 dogfood all hit it. Claude Code's Task tool has no such tight cap. Expose maxTurns as an optional param (default 20 unchanged) so the model can raise it (e.g. 40) for complex multi-step tasks. Threaded through both the foreground delegate + lifecycle spawn paths.

maxTurnsas an optional param (default 20 unchanged) so the model can raise it (e.g. 40) for complex tasks. Threaded through the foreground delegate + lifecycle spawn paths.Why
Dogfooding fleet to build SPEC-6-1 — Tasks 5/6/10 all hit the 20-turn budget. The controller needs a way to raise the cap per-task.
Verification
313/313 tests pass, typecheck clean. Default unchanged (back-compat).
