   ref: #1058
   
   ### What
   
   Increase coverage for `qdp/qdp-core/src/readers/torch.rs`.
   
   Current reported coverage for the file is still zero in the main llvm-cov 
run:
   
   - Function coverage: `0.00% (0/4)`
   - Line coverage: `0.00% (0/41)`
   
   ### Why
   
   We already have `qdp/qdp-core/tests/torch_io.rs`, but the current coverage 
still suggests that constructor and reader state transitions in 
`readers/torch.rs` are not being exercised in the main coverage workflow.
   
   This leaves basic reader behavior under-tested.
   
   ### How
   
   Add or adjust tests so that the main coverage run hits the reader 
implementation directly.
   
   Suggested coverage targets:
   
   - `TorchReader::new()` succeeds for an existing `.pt` file
   - `TorchReader::new()` fails for a missing file
   - `read_batch()` rejects a second read with `Reader already consumed`
   - `get_sample_size()` and `get_num_samples()` are asserted after a 
successful read
   - if the coverage job excludes the `pytorch` feature, add coverage for the 
non-feature `NotImplemented` path or document that gap clearly in the test 
approach
   
   This issue is done when `readers/torch.rs` shows real coverage improvement 
in `cargo llvm-cov`.
