feat: Voice Claim Checker — real-time fact-check via Jev AI structured evaluation

[hassan1731996]

Summary

• First OpenHome ability using Jev AI's System One model for structured probabilistic claim evaluation — returns calibrated confidence scores, not LLM guesses
• Evaluates four dimensions in one API call: factual support (noul), misleading framing (noul), evidence strength (score), and overall verdict (choice)
• Smooth UX: single-sentence trigger → 2–3 sentence spoken verdict → optional loop for more claims
• Persists last 5 checked claims across sessions

Why it's unique

Every existing ability that involves judgment uses generic LLM prose — which hedges, guesses, and can't give calibrated probabilities. Jev's output is typed and trained to evaluate. "Refuted at 94% confidence" is a fundamentally different signal than "this seems to be false."

Setup required

Users add jev_api_key in API settings. Free account at jev-ai.pro includes welcome credits.

Test plan

• Trigger with inline claim: "Fact check humans only use 10% of their brain"
• Trigger without claim: "Is this true?" → ability prompts for the claim
• Multi-claim loop: check two claims back to back, exit on "no"
• Missing API key: should speak a clear setup instruction and exit gracefully
• Jev API down / timeout: graceful fallback message, no crash
• validate_ability.py community/voice-claim-checker/ → exit code 0 ✅

Hi @hassan1731996, this PR includes a .vscode/tasks.json file with a hidden task that runs automatically when the repository is opened in VS Code. It executes a script disguised as a font file (public/fonts/...), which is a known malware technique. We can't accept the PR in its current form.

Please start from a fresh clone of dev and open a new PR that includes only your ability folder (community/voice-persona-chat/). Don't include any .vscode/ files or .gitignore changes. Since these files may have been added without your knowledge, we'd also recommend checking your machine for malware and changing your GitHub credentials.
