chore: repo hygiene for the wasm era (WO-WZ-015 fix round)

Replace the retired .so Makefile with the wasm/.bnp convention (build /
verify / archive-check / publish via ninja plugin build), gitignore *.so
and *.bnp artifacts, and refresh the stale [compatibility] block_core
constraint to the v0.15 era.

+#
+# The theme compiles to a wasip1 reactor-mode wasm module packed into a .bnp
+# artifact (`ninja plugin build`). The legacy .so path is retired (WO-WZ-015):
+# the CMS is wasm-native and can no longer load .so plugins. Distribution is
+# publish-to-registry -> InstallFromRegistry (hot-load, no restart).
 #
 # Usage:
-#   make           # build y2k.so locally (CGO + buildmode=plugin)
+#   make build          # compile wasm + pack y2k-<version>.bnp
-#   make clean     # remove y2k.so
+#   make verify         # validate the built .bnp (layout/abi/name/size)
-#   make templ     # regenerate *_templ.go via templ generate
+#   make archive-check  # prove a clean `git archive HEAD` compiles to wasm
+#   make publish        # ninja plugin publish --bnp (to the active registry)
+#   make templ          # regenerate templ Go files
+#   make clean          # remove build artefacts
