Summary

  • raise the fixed PTY effect table from 4 to 32 entries
  • preserve bounded allocation and explicit refusal behavior
  • expand runtime tests for capacity, reuse, and cleanup

A real consumer exposed the old ceiling by supporting 32 local terminals while the SDK refused the fifth PTY. The equivalent patch is shipping in Phux Cockpit v0.12.0; this PR brings the capacity contract upstream.
