M9 fixtures

M9 adds comptime type parameters and monomorphization.

ok*.fe must compile; bad*.fe must fail according to the first-line marker. defscope/ and okscope/ are multi-unit definition-scope tests and require M8 imports. okscope/ verifies that an exported generic may use its definition unit's private helper through .fei support metadata.

Coverage:

• generic functions and structs,
• multiple and duplicate instantiations,
• type aliases as comptime type values,
• T == U and @is_int(T) in comptime,
• instantiation-time operation errors,
• arity/type-argument errors,
• runtime type values forbidden,
• definition-unit name lookup,
• recursive instantiation depth limit.
• rejection of user value generics and generic type inference,
• same-instance recursive request reuse and selected-out comptime if semantic skipping.

M9's DOS gate should additionally inspect generated fe_generics.c: okdedup.fe must emit one body for the repeated (id, i32) instantiation.
