Add discern

[doeixd]

Adds one object to the projects array in data/projects.json. No other files touched — README.md and site/index.html are left for CI. npm run validate passes (906 entries valid).

Disclosure: I built and maintain discern. It was developed with substantial AI assistance, with the design and the API reviewed by hand.

Where Jev fits

Effect v4 ships Decision / DecisionModel — typed semantic observations (classification, probability, ordered rating). discern is the control-flow layer over that vocabulary: the semantic counterpart to Effect's Match. Jev is the provider, reached through @effect/ai-typesafe with TypeSafeDecisionModel.layer({ model: "jev-latest" }) — see examples/headline.ts and test/integration.types.ts.

The library owns the thresholds: an answer below them takes an explicit Uncertain branch instead of being rounded to the top label, procedure routing skips the model call entirely when deterministic predicates leave one candidate, and recording/replay/caching/budgets are DecisionModel middleware.

integrations felt right over sdks — it is not a client for the TypeSafe API, it is Jev inside a framework. Happy to move it if you'd rather it sit elsewhere.

Not an empty repo: MIT licensed, published to npm, 48 tests that run offline with no API key (npm test).

Landed on main as 5283fd3 with you as the commit author, now live on https://awesomejev.com. Closing rather than merging because every PR appends to the same data file and they conflict with each other; landing directly keeps your authorship. Thanks!
