giles f3e516feec sx-http: CSSX source before components in defs, JIT closure bug identified ...

Move client library sources (cssx.sx) before defcomp/defisland
definitions in component-defs so defines are evaluated first.

Identified root cause of CSSX "Not callable: nil" errors:
JIT compiler captures free variable values at compile time instead of
looking them up at runtime from vm_globals. When ~cssx/tw's JIT code
calls cssx-process-token, it uses the compile-time snapshot (nil)
instead of the runtime value (lambda). The function IS in global_env
(type-of returns "lambda") but the JIT bytecode doesn't see it.

Fix needed: JIT compiler should emit GLOBAL_GET instructions for free
variables that reference vm_globals at runtime, not capture at compile.
