GeoFLAC/DynEarthSol#92 merged — docs: clarify goSPL coupling limitations

Summary

• Adds a "Known Limitations" section to gospl_driver/README.md covering three behaviors clarified while reviewing the coupling scheme for the manuscript:
  • The coupling interval (gospl_coupling_interval_in_yr) only gates when coupling fires; DES's actual dt is passed to goSPL as-is, not clamped to the configured interval.
  • A remesh occurring mid-coupling-interval doesn't disturb the coupling clock or reset goSPL's elevation state, but the time-averaged-velocity calculation's node-count-only guard can miss a remesh that happens to preserve the top-boundary node count, silently differencing unrelated nodes.
  • The goSPL mesh domain (padding around the DES model's initial surface extent) is fixed at initialization and never regenerated, so the padding fraction effectively bounds how much lateral extension the DES model can accumulate before hitting boundary artifacts.
• Fixes a stale comment on GoSPLDriver::needs_elevation_reset in gospl-driver.hpp that incorrectly claimed the flag is re-armed after remeshing (it is not, in the current implementation).
