Add jev-canvas

[gaborishka]

Project: https://github.com/gaborishka/jev-canvas

Where Jev fits: one Decisions API request per partial transcript answers the typed questions (is this a command, is it complete, action, shape, colour, target, place, size) and deterministic code applies the thresholds and edits the canvas.

• I added one object to data/projects.json and ran npm run validate — the object is added, and I checked the file still parses as valid JSON, but I did not run npm run validate locally.
• I did not commit README.md or site/index.html (CI regenerates them)
• I am the author, or I linked where the project was announced

Adds jev-canvas (I built and maintain it).

What it is: a browser demo where you draw on a tldraw canvas by speaking while pointing a finger at the screen (MediaPipe hand tracking + Web Speech API).

How it uses Jev: one Decisions API request per partial transcript with typed questions (noul: is_command, complete; choice: action, shape, colour, target, place, text span; score: size). Thresholds, pointing-word capture and execution are plain code. Questions: shared/questions.js, policy: shared/policy.js.

Evidence: scripts/probe.js runs 18 spoken commands (10 English, 8 Ukrainian) against the live API: 18/18 correct, 300–550 ms, about 1,900 input tokens per request. The README notes two findings: short Ukrainian imperatives scored is_command at 12% until the question said the speaker may use Ukrainian (87% after), and a visible finger alone pulls where=point up, so code only honours it when a pointing word was spoken.
