chore: use the organisation-wide CLA (#107)

Contributors sign the Structured World Contributor License Agreement once at https://sw.foundation/cla, and the Structured World CLA app sets the CLA status on every pull request. The repository's own CLA Assistant workflow and CLA.md are removed; nobody had signed the old document. .gitignore no longer lists local working files, which are excluded per clone.

Closes #106

 ## Contributor License Agreement (CLA)
 
-Before a first pull request can be merged, you sign the
-[Contributor License Agreement](CLA.md). Signing happens in the pull request:
-a bot posts the request, you reply with the sentence it asks for, and the
-signature is recorded in `signatures/` in this repository. It is a one-time
-step per GitHub account.
-
-In short, the CLA says that you keep the copyright in your contribution, that
-you grant the project's copyright holder (and any successor the copyright is
-assigned to) a perpetual, worldwide, royalty-free, irrevocable licence to use,
-modify, distribute and sublicense it under any terms, and that you are entitled
-to make that grant. The project promises in return that your contribution stays
-available under Apache-2.0 and that you remain free to do anything with your
-own work.
-
-If your employer owns what you write, ask them to confirm they permit the
-contribution before you sign.
