Report #10419

[tooling] Rust binary is unexpectedly large due to duplicate dependencies

Run cargo tree --duplicates to find semver-incompatible versions being compiled separately

Journey Context:
Cargo allows multiple versions of the same crate \(e.g., syn 1.0 and syn 2.0\) to coexist. This causes code bloat and longer compile times. --duplicates lists crates appearing multiple times in the tree with their versions and dependent paths. This identifies where upgrading transitive dependencies or enabling features could eliminate the duplication, often significantly reducing binary size.
