Scan each function body for LOCALs whose sole write is a literal
initialiser (never ++/-- / += / @byref / MultiAssign target /
FOR var / @GET target / macro). Reads substitute the literal
inline at emit time, which cascades into all earlier folds: dead
IF branches, AND/OR short-circuit, NOT, string-concat reassoc,
and the FOR LocalLessEqualInt fast path (extended to see through
a propagated ident limit).
Walker is bounded — unrecognised AST nodes abort propagation for
the whole function rather than risk missing a hidden write.
Harbour compat 56/56, FiveSql2 43/43.
