Constant MAX_RESOLVED_NAME_LEN 

pub const MAX_RESOLVED_NAME_LEN: usize = 128; // 128usize

Phase 305 W3 (issue 0255) — the ONE name-resolution seam: ROS 2 source-name expansion (~/relative → FQN, ns=/ collapse) + launch remap substitution (exact-FQN match, first rule wins; no wildcards). Implemented in nros_node::names so both the Rust ExecutorSink and the C-ABI executor-side remap table share one lowering; re-exported here next to SourceNameKind as the source-metadata-level entry point. Maximum bytes in a fully-qualified resolved entity name. Matches nros::node_metadata::METADATA_STRING_CAPACITY (the source-name bound entering the resolution seam).
