Description of your pull request goes here. **Provide examples and/or screenshots** if your changes affect the user experience. --> Part of https://github.com/nushell/nushell/issues/12963, step 2. This PR refactors changes the use of `expression.span` to `expression.span_id` via a new helper `Expression::span()`. A new `GetSpan` is added to abstract getting the span from both `EngineState` and `StateWorkingSet`. # User-Facing Changes <!-- List of all changes that impact the user experience here. This helps us keep track of breaking changes. --> `format pattern` loses the ability to use variables in the pattern, e.g., `... | format pattern 'value of {$it.name} is {$it.value}'`. This is because the command did a custom parse-eval cycle, creating spans that are not merged into the main engine state. We could clone the engine state, add Clone trait to StateDelta and merge the cloned delta to the cloned state, but IMO there is not much value from having this ability, since we have string interpolation nowadays: `... | $"value of ($in.name) is ($in.value)"`. # Tests + Formatting <!-- 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 > toolkit check pr > ``` --> # After Submitting <!-- If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary. This will help us keep the docs up to date. --> |

nu-cmd-extra
The commands in this crate are the extra commands of Nushell. These commands are not in a state to be guaranteed to be part of the 1.0 API; meaning that there is no guarantee longer term that these commands will be around into the future.
For a while we did exclude them behind the --features extra compile time
flag, meaning that the default release did not contain them. As we (the Nushell
team) shipped a full build including both extra and dataframe for some
time, we chose to sunset the extra feature but keep the commands in this
crate for now. In the future the commands may be moved to more topical crates
or discarded into plugins.
