Spec-gate finding 4: a GET failure on src/rune/__init__.py was skipped like
an optional surface, so a bump PR could silently bump nothing. The version
surface is now fatal (exit 1 before any PR is filed); the other surfaces
stay optional (pattern absent — skip). The surface-edit loop is extracted to
apply_surface_edits() with an api callable seam for testing.
Red evidence: 4 new tests failed (no is_surface_fatal/apply_surface_edits;
abort test found no SystemExit). Green: 10/10.
