_⚠️ Potential issue_ | _🟡 Minor_

**Add cleanup for temporary file.**

The code creates a temporary file with `delete=False` but never explicitly cleans it up. This could lead to accumulating temporary files on disk.



<details>
<summary>🧹 Proposed fix to add cleanup</summary>

```diff
 # In run_chain()
 config_source = args.config
 if config_source == '-':
     import tempfile
+    import os
     stdin_content = sys.stdin.read()
     # Write to temp file since YAML loader expects a file
     with tempfile.NamedTemporaryFile(mode='w', suffix='.yaml', delete=False) as f:
         f.write(stdin_content)
-        config_source = f.name
+        temp_path = f.name
+    try:
+        config_source = temp_path
+        # ... rest of YAML loading and processing ...
+    finally:
+        os.unlink(temp_path)
```

Alternatively, if the YAML loader supports file-like objects, consider passing `io.StringIO(stdin_content)` directly to avoid temporary files altogether.

```
In `@issues/subtask-3-stdin-stdout.md` around lines 93 - 103, The run_chain()
branch that handles config_source == '-' creates a temp file with
tempfile.NamedTemporaryFile(delete=False) but never removes it; update
run_chain() to either avoid writing a temp file by passing
io.StringIO(stdin_content) (if the YAML loader accepts file-like objects) or, if
a real file is required, ensure the temp file is unlinked after loading (use
os.unlink on the NamedTemporaryFile.name in a finally block or use
NamedTemporaryFile(delete=True) and reopen if needed) so the temporary file is
always cleaned up; reference the config_source handling block and the
tempfile.NamedTemporaryFile usage when making the change.
