Add .sxbc s-expression bytecode format

Browse Source 
Bytecode modules are now serialized as s-expressions (.sxbc) in addition
to JSON (.sxbc.json). The .sxbc format is the canonical representation —
content-addressable, parseable by the SX parser, and suitable for CID
referencing. Annotation layers (source maps, variable names, tests, docs)
can reference the bytecode CID without polluting the bytecode itself.

Format: (sxbc version hash (code :arity N :bytecode (...) :constants (...)))

The browser loader tries .sxbc first (via load-sxbc kernel primitive),
falls back to .sxbc.json. Caddy needs .sxbc MIME type to serve the new
format (currently 404s, JSON fallback works).
