Charlie Marsh f2b2e5b2a9 Make exec-server file reads cancellable between chunks (#49696) ...

## What changed

Run direct `read_file` operations in a blocking task with bounded read chunks and cancellation checks. Dropping the async caller cancels further reads between chunks. Preserve the 512 MiB size limit, symlink-following options, and regular-file validation.

## Testing

Add regression coverage for 4 MiB reads and oversized-file rejection with both symlink-following options, cancellation after the first chunk, and FIFO rejection without waiting for a writer.
