Beautify the README; fix health endpoint OpenAPI auth

[martsokha]

Two changes:

1. Beautify the README

Restyles the README to match the Nvisy Studio README:

• A centered hero — the shared brand logo, a bold tagline, a Build / Release / Security / License badge row (pointed at this repo's actual workflows), and a nvisy.com · docs.nvisy.com · app.nvisy.com link row.
• The active-development warning callout, then consistent sections: Features, Requirements, Quick start, Commands (real Makefile targets), Documentation (the four docs/ files), Contributing, License, Support.

Adds the shared brand logo at .github/assets/logo.png (byte-identical to Studio's). Every linked path resolves to a file that exists.

The hero image and workflow badges render on GitHub, not in a local Markdown preview.

2. Fix the health endpoint's OpenAPI auth requirement

/health/ is mounted on the public router and accepts unauthenticated requests (an authenticated caller gets a real-time health check; an unauthenticated one gets the cached status). But because the handler extracted Option<AuthState>, aide's blanket Option<T> OperationInput delegated to AuthState's impl and stamped a required Bearer requirement — so the spec wrongly marked the endpoint auth-required, which misled SDK clients.

Adds an OptionalAuth extractor (its own file) that carries the same optional value but declares the token as optional in the spec — an empty security requirement (no auth) alongside the Bearer one. The health handler uses it; a unit test asserts the emitted security offers the unauthenticated alternative.
