fix(core/abi): bump ABI_VERSION to 13 for punktfunk_connection_send_pen

Browse Source 
The pen P0 work added a new embeddable C entry point (punktfunk_connection_send_pen)
but left ABI_VERSION at 12 — the value 0.18.0 shipped. Per the project's convention
(0.18.0 bumped to 12 for the additive cursor channel), additive C-surface growth bumps
the ABI so embedders can gate on the new symbol. Regenerated include/punktfunk_core.h
via cbindgen (cargo build -p punktfunk-core); WIRE_VERSION is unchanged (pen is
capability-gated on HOST_CAP_PEN).
