lowerVarDecl (unannotated) and lowerDestructureDecl now clear target_type around the initializer lowering: a declaration without annotation provides no target, so int/float literals take their spec defaults (s64/f64) instead of the enclosing function's implicit-return type (x := 0 in a -> s8 fn was s8; big := 3000000000 in -> s32 silently wrapped to -1294967296). Regression: examples/0173-types-int-literal-default-s64.sx. The remaining explicit-annotation wrap (x : s8 = 300) is filed as issue 0112.

// Integer literals default to s64 regardless of context: an unannotated
|
|
// `x := <int literal>` local stays s64 even inside a function whose return
|
|
// type is a narrower integer (the implicit-return target must not type the
|
|
// body's declarations), and a large literal initializer keeps its value.
|
|
// Also covers destructure decls (`a, b := ...`), which share the same rule.
|
|
// Regression (issue 0111): these locals adopted the enclosing fn's return
|
|
// type (s32/s8), silently wrapping `big := 3000000000` to -1294967296.
