fix: resolve critical printf syntax error blocking cargo-wrt build

- Fix malformed printf statement in wrt-error/src/recovery.rs:194
- This was preventing cargo-wrt from building, which blocked CI tooling
- wrt-error crate now builds successfully
- This should resolve the 'cargo-wrt: command not found' errors in CI
