Narrow Bare Rescue

Turn rescue _ -> fallback into rescue _ in [ExceptionType1, ExceptionType2] -> fallback so programmer bugs propagate while known failure modes stay handled.

Why this matters

Bare rescues (rescue _ ->, rescue e -> — any form without an in clause) swallow every exception, including UndefinedFunctionError from typos, KeyError from misspelled map keys, and CompileError from bad HEEx templates. The symptom isn't a stack trace — it's a silent or a fallback. Bugs that should surface in tests or error reporters become quiet degradations.
