hashtree-nostr

Hashtree-native Nostr event indexes for Rust.

This crate stores signed Nostr events as deterministic content-addressed blobs and maintains thin B-tree indexes for lookups like:

• event_id -> event blob
• author/time scans
• author/kind/time scans
• replaceable and parameterized-replaceable event winners

The layout is kept interoperable with the TypeScript @hashtree/nostr implementation. The manifest exposes the event-id index under by-id.
