Determine anonymous function wrapper offset at runtime

Editor assessment

`fix: determine anonymous function wrapper offset at runtime` names the mechanism and the corrected strategy concretely; the footer `close #2265` is well-formed and links the failure it repairs, and the trailing PR reference is routine. A scope for the transform or preload area is missing, a minor gap in an otherwise precise subject. No body appears, but for a one-aspect fix whose subject states the approach, none is clearly required. Fix matches the bug. Imperative verb, no trailing period, moderate length. Clear and correct — publishable with the small scope omission.
