Fix field name clashing with namespaced virtual field names

- Prefix built-in trigger fields with __builtin_ namespace
- Prefix custom trigger fields with __trigger_{slug}_ namespace
- Completely eliminates field name conflicts between triggers
- Maintains backward compatibility with existing workflows
- Virtual fields transparently handle the namespacing
