Update README with badge and project description

[senamakel]

Added a badge and enhanced the project description.

Summary

• What changed and why.
• Keep this to 3-6 bullets focused on user-visible or architecture-impacting changes.

Problem

• What issue or risk this PR addresses.
• Include context needed for reviewers to evaluate correctness quickly.

Solution

• How the implementation solves the problem.
• Note important design decisions and tradeoffs.

Submission Checklist

• Unit tests — Vitest (app/) and/or cargo test (core) for logic you add or change
• E2E / integration — Where behavior is user-visible or crosses UI → Tauri → sidecar → JSON-RPC; use existing harnesses (app/test/e2e, mock backend, tests/json_rpc_e2e.rs as appropriate)
• N/A — If truly not applicable, say why (e.g. change is documentation-only)
• Doc comments — /// / //! (Rust), JSDoc or brief file/module headers (TS) on public APIs and non-obvious modules
• Inline comments — Where logic, invariants, or edge cases aren’t clear from names alone (keep them grep-friendly; avoid restating the code)

(Any feature related checklist can go in here)

Impact

• Runtime/platform impact (desktop/mobile/web/CLI), if any.
• Performance, security, migration, or compatibility implications.
