Stdlib-candidate Reset (#986)

On today's call, we decided to reset stdlib-candidate and start fresh
(and try to manage it more effectively going forward).

This PR is that reset, along with an updated README for the new module.

The main thing that needs reviewing here is the
[README](https://github.com/nushell/nu_scripts/pull/986/files#diff-680b95f9d9e2e9c06ee31ff6835e5d29ba11703ef7252bd42ecafa433767e0c6).

+# std-lib candidate
+
+This is the deprecated `stdlib-candidate` module. Please see the [new version](https://github.com/nushell/nu_scripts/tree/main/stdlib-candidate). If you have a submission here, you can move it to the new repo. Please refer to the [README](https://github.com/nushell/nu_scripts/blob/main/stdlib-candidate/README.md) there for the process.

 # std-lib candidate
 
-This folder is where we can add scripts that might want to be in std-lib at some point. It can serve both as a holding place for scripts that are waiting on nushell changes, as well as a place to develop and discuss such scripts.
+## Overview and Requirements
+
+This module includes potential candidate commands (and other definitions) for inclusion in the Standard Library (`std`) that is built in to Nushell. As a general guideline, candidates should:
+
+* Be general purpose
+* Have broad appeal to other users
+* Include doc comments for definitions and parameters that can be used with `help <command>`
+* Include tests
+
+The last two (doc and tests) do not need to be in place at the time of the initial inclusion in `stdlib-candidate`, but are, of course, required in order to promote to `std`.
+
+## Showcase and Discussion
+
+While primary feedback should take place in the PR, we have also established a [Drawing Board Discord Showcase](https://discord.gg/C3eMKV58MQ) which can be used for several purposes:
+
+* Ideation before a PR is submitted
+* Raise awareness of the PR
+* Short-term questions and discussion
+
+Note: The Drawing Board is not just for stdlib-candidate. Please tag your topic with `std-library` if it is about a Standard Library idea.
+
+## Promotion Evaluation
+
+In general, PRs will be evaluated after they have been trialed for a sufficient period, expected to be around 2 months. After that period, the feature may be:
+
+* Promoted to `std`
+* Removed from `stdlib-candidate`
+* Or changes may be requested and then reevaluated later
+
+## NUPM Note
+
+When submitting a PR, please bump the module's `nupm.nuon`.
+
+# Previous Repo
+
+Note: As of December 2024, the candidate module has been "reset" to start fresh. The previous version has been moved to https://github.com/nushell/nu_scripts/tree/main/stdlib-candidate-old
