When a branch relocation has a non-zero addend (e.g., `bl _func+16`), the linker was incorrectly computing `stub_address + addend` instead of `function_address + addend`. This caused the branch to land in the wrong location (past the stub section) rather than at the intended interior point of the function. The fix checks for non-zero addends on branch relocations and uses the actual symbol VA in those cases. This makes sense semantically—branching to an interior offset implies reliance on the original function's layout, which an interposed replacement wouldn't preserve anyway. Added test `arm64-branch-addend-stubs.s` that verifies the correct behavior using `-flat_namespace` (which makes local symbols interposable and thus routed through stubs).
