fix: use restrict_in_place for cascade restrictions in Diagram

Cascade restrictions stored as plain lists (for OR semantics) were
being directly assigned to ft._restriction, causing list objects to
be stringified as Python repr ("[' condition ']") in SQL WHERE clauses.

Use restrict_in_place() which properly handles lists as OR conditions
through the standard restrict() path. Also fix version string to be
PEP 440 compliant.
