agra 010e644897 fix(R1): own const_decl pending alias wins over flat imports (issue 0107) ...

When a module declares `A :: B; B :: u64;` and both a flat import and a
namespaced import export `B :: u8`, the flat import's B was discovered by
flatTypeAuthorCount before the own B :: u64 was processed — binding A to
u8 and silently truncating values.

Fix: ownConstDeclIsPendingAlias guard added to selectNominalLeaf between
the own-alias check and the flat-import walk. If the querying module has
an own const_decl for the name that is not yet in type_aliases_by_source,
return .pending so the forward-alias fixpoint resolves it correctly.

Regression: examples/0830-modules-flat-ns-same-name-forward-alias.sx
(x : A = 300 prints 300, not 44). 541/541 tests pass.
