handoff: Fix lint in file-pattern extraction

Amolith created 

- Remove useless regex escape on closing paren
- Replace while/exec loop with for/matchAll to avoid assignment in
expression and implicit-any let
- Change trailing boundary group from consuming to lookahead so
adjacent files separated by a single space are no longer skipped
