BootAuditStorage class abstract interface

Synchronous key/value backend used by BootAudit to persist its trail across app boots.

Implementations must be synchronous so BootAudit.log can run from the very first line of main() without awaiting a future. The contract is deliberately minimal — JSON-encoded strings in, JSON-encoded strings out.

Bundled implementations:

• InMemoryBootAuditStorage — process-local, lost on restart. Useful for tests and non-web platforms where persistence isn't wired yet.
• LocalStorageBootAuditStorage — browser localStorage on web, no-op on non-web (selected at compile time via dart.library.js_interop).

To plug in a different backend (e.g. SharedPreferences, a file on disk, IndexedDB), implement this interface and pass an instance to the BootAudit constructor.
