March 2026: Implemented opt-in Sysinfo tab behind a feature flag in the System Monitor, with UI cleanup and a robust tab numbering sequence. Resolved a transitive dependency conflict between libmacchina and sqlite3-sys by gating sqlite-related dependencies behind the new sysinfo feature, preventing conflicts for users building with sqlx. Hid SYS tab by default to reduce UI noise, and exposed the sysinfo feature to downstream crates (e.g., cu-consolemon) to enable opt-out. Updated TAB_DEFS-driven numbering to keep 1,2,3… order intact regardless of enabled features. Improved developer experience by addressing clippy warnings when the feature is off. Business impact: fewer binary conflicts, safer feature opt-in, cleaner UI, and clearer upgrade path for system monitor improvements.
