Implement truncate_test.go + workload scenarios for truncate, ftruncate

- truncate-basic: tests SYS_TRUNCATE (path-based) via syscall.Truncate
- truncate-ftruncate: tests SYS_FTRUNCATE (fd-based) via syscall.Ftruncate
- Both syscall wrappers use direct SYS_* calls on amd64 (no *at wrapping)

Task #343
