fix(bild): per-module cp overwrites with -f and chmod after each copy
When building per-module derivations, copying dependency .hi files
was failing silently because: 1. First dep copies read-only Alpha.hi
from nix store 2. Second dep also has Alpha.hi (transitive dep) and
tries to overwrite 3. cp fails with permission denied but error is
hidden by '|| true'
Fixed by: - Add -f flag to cp to force overwrite - Run chmod -R +w
after each dependency copy - This allows later deps to overwrite
shared files like Alpha.hi
Tested: Biz/Que/Host.hs now builds successfully with per-module
derivations
