License validation for Logicaffeine verification.

Uses the Stripe-based license system. License keys are Stripe subscription IDs (sub_* format) validated against the Logicaffeine API.

Usage

use logicaffeine_verify::LicenseValidator;

let validator = LicenseValidator::new();
match validator.validate("sub_abc123xyz") {
    Ok(plan) => println!("License valid: {} plan", plan),
    Err(e) => eprintln!("License error: {}", e),
}

2. Cache check: Return cached result if fresh (< 24 hours)
3. API validation: Call api.logicaffeine.com/validate
4. Fallback: Use stale cache if network fails

Caching

Results are cached for 24 hours at:

• macOS/Linux: ~/.cache/logos/verification_license.json
• Windows: %LOCALAPPDATA%\logos\verification_license.json
