rebase: raise the module agent turn budget to 400

A flash-class module agent needs roughly 2.3x the turns of the pro tier on
the same module (140+ turns vs 62), most of it shell exploration before the
first edit. At the old ceiling of 150 the agent loop was truncated and
RESTARTED from scratch, discarding its accumulated context -- one module
burned 63 minutes across three truncated loops without finishing.

400 lets a loop reach a conclusion instead of being cut off mid-investigation.
Exhausting the budget was never fatal (the engine restarts the loop rather
than failing the module), so this is a throughput fix, not a correctness one.
