1. parse-trigger-spec: strip [condition] from event names, store as
"filter" modifier (e.g. keyup[key=='s'] → event="keyup", filter=...)
2. bind-event: evaluate filter conditions via JS Function constructor
when filter modifier is present
3. bind-inline-handlers: map afterSwap/beforeRequest etc. to sx:*
event names (matching what the engine dispatches)
4. bind-inline-handlers: detect JS syntax in body (contains ".") and
eval via Function instead of SX parse — enables this.reset() etc.
