revert: restore #![allow(dead_code)] - clippy -D warnings treats warn as error The #742 PR changed #![allow(dead_code)] to #![warn(dead_code)], but CI runs clippy with -D warnings which turns warnings into errors. This caused CI failures across multiple PRs. Reverting to #![allow(dead_code)] until the dead code is actually cleaned up. The 189 warnings in ecstore should be fixed incrementally by deleting dead code and adding item-level allows, not by changing the crate-level policy.
