Fix keyboard shortcuts + trigger filter + sx-on event mapping

1. parse-trigger-spec: strip [condition] from event names, store as
   "filter" modifier
2. bind-event: native SX filter for key=='X' patterns (extracts key
   char and checks event.key + not-input guard)
3. bind-event from: modifier: resolve "body"/"document"/"window" to
   direct DOM references instead of dom-query
4. sx-platform-2.js: global keyboard dispatch — WASM host-callbacks
   on document/body don't fire, so keyboard triggers with from:body
   are handled from JS, calling execute-request via K.eval
5. bind-inline-handlers: map afterSwap/beforeRequest to sx: prefix,
   eval JS bodies via Function constructor
