Adds concepts/sounio.scroll for Sounio, a self-hosted research language for scientific computing.

I am the language's author. Status is cited as Sounio 3.0 (pre-release). Version-number fields are omitted so the record does not invent a current release number.

Verified sources: the official site, the repository README, examples/hello.sio, the units-and-uncertainty guide, and git history (first commit b6d03ae, 2025-12-25; GitHub repo created 2025-12-24).

Fields omitted for lack of a public source, or to avoid an unverified claim:

• latestVersion (no version number is included)
• country and lab
• paper (the public preprint describes a retired compiler, not the current system)
• repoStats / star and issue snapshots
• a generic "algebraic effects" feature flag: the official effect guide documents declared effects in the signature and Madaros handlers, and PLDB has no hasAlgebraicEffects measure. The description therefore says "declared effects".
