Highlights

• SQLite store — SQLite backend next to Redis behind a shared Store abstraction; new_sqlite / lnr_new_client_sqlite plus updated C and Python bindings.
• Delivery semantics — send_to / send_all support at_least_once (Rust examples & benches, C++ optional flag, tests for isolated SQLite with false).
• Benchmarks & tests — Pair benchmarks for Redis and SQLite; fix for shared-catalog SQLite bench; Python integration tests aligned with Redis scenarios on a shared DB.

Documentation & packaging

• Expanded developer guides (EN, partial RU), assets under docs/img, README and debug/test run instructions.
• Crate packaging updates: include/ and trimmed exclude in Cargo.toml.
