# Description
Closes#13765
Transpose now checks if the input consists entirely of records before
doing its things, which is fine since it already `.collects()` all of
its input already.

# Tests + Formatting
Adds `rejects_non_table_stream_input` test to cover regressions.
<!--
Don't forget to add tests that cover your changes.
Make sure you've run and fixed any issues with these commands:
- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` to run the
tests for the standard library
> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically

# Description
This PR aims to close#14027, in which it was noticed that the transpose
command "swallows" error messages.
*Note that in exploring the linked issue, [other situations were
identified](https://github.com/nushell/nushell/issues/14027#issuecomment-2414602880)
which also produce inconsistent behaviour. These have knowingly been
omitted from this PR, to minimize its scope, and since they seem to have
a different cause. It's probably best to make a separate issue/PR in
which to tackle a broader scan of error handling, with a suspected
relation to streams.*
# User-Facing Changes
The user will see errors from deeper in the pipeline, in case the errors
originated there.
# Tests + Formatting
Toolkit PR check was run successfully.
One test was added, covering this exact situation, in order to prevent
regressions.
The bug is relatively obscure, so it may be prone to reappear during
refactorings.
This PR just tidies up some tests by removing unused code:
1. If the filesystem is not touched, don't use the filesystem
playground/sandbox
2. If the filesystem is not touched, don't specify the `cwd`
3. If the command is short, don't bother wrapping it in `pipeline()`
4. If the command doesn't have quotes, don't bother with a `r#"..."#`
raw string
Part of #8670.
