Fix island state loss on SX navigation + cache busting

Island markers rendered during SX navigation responses had no
data-sx-state attribute, so hydration found empty kwargs and path
was nil in the copyright display. Now adapter-dom.sx serializes
keyword args into data-sx-state on island markers, matching what
adapter-html.sx does for SSR.

Also fix post-swap to use parent element for outerHTML swaps in
SX responses (was using detached old target). Add SX source file
hashes to wasm_hash for proper browser cache busting — changing
any .sx file now busts the cache. Remove stale .sxbc bytecode
cache files.
