Beerust 1.3.0

Fixed

• bee_tsdb / bee_graph: enabling one backend feature on its own did not compile — the shared http_client helper lived inside the feature-gated influxdb / neo4j modules, so a build with only iotdb / questdb / arangodb / nebulagraph hit an unresolved import; it now lives in each crate's own crate::http (gated over exactly the backends that use it), and every single-backend feature builds on its own — the feature matrix was re-run item by item
• bee_router: the optional security feature moved to security-rust 4.0.0 — Scanner / DetectionResult / AttackCategory / Severity keep the 1.x shape, so no source change was needed on the bee_router side; the capability surface grew: 32 built-in detectors (new: format_string, log4shell, HPP, formula_injection, reDoS), detectors are now tiered strong/weak (weak signals are fixed at Severity::Low), and Scanner::assess was added. The filter still decides "block on any hit", so weak signals (e.g. a repeated query parameter) are now blocked as well — there is no longer an injection point for a custom scanner; to let them through, build your own Filter around SecurityFilter::scanner(). The dependency graph now carries a single security-rust 4.0.0 instead of 1.x alongside 4.x; the docs were updated to match
• duplicates merged: bee_tsdb / bee_graph / bee_search each keep one copy of the connection and error-mapping helpers (the backend name is now passed by the caller, error texts unchanged; aggregation_fn moved to bee_tsdb's lib), bee_graph's backtick / esc joined its http module, bee_orm extracted dedup_pk_values / index_rows_by and the migrate foreign-key clause, bee_session::refresh now reuses load, and bee_config's watch_path absorbed the remaining wait_for_change call path; bee_search error messages regain the backend name, and bee_kv's test stub is now private to its tests
• public API removed (hence the minor version): Context::set_params / param, SecurityFilter::with_scanner, Traversal::edge_labels → edge_label: Option<String> (all three backends already took only the first label — behavior unchanged), GraphError::EdgeNotFound, ConfigError::ParseError / TypeMismatch, bee_config::watch_path_timeout, and bee_logs::Logger::async_ (a switch init() never read) — all of them with zero callers
• dead dependencies removed: bee_router (tracing / http / bee_config / bee_logs), bee_session (async-trait), bee_config_macro (proc-macro2), and the duplicate dev serde in bee_tsdb / bee_graph / bee_search
