v2026-03-11.2 - Aggregation, ICMP Hardening & Smokeping Default

Highlights

• Connection Monitor sample aggregation with tiered retention - raw samples are automatically compressed into 1-min, 5-min, and 1-hour buckets as they age, enabling 30d and 90d views without storage bloat.
• New 30d/90d range buttons with resolution indicator and min/max band rendering for aggregated data.
• Resolution-aware CSV export matches the active chart view.
• ICMP probing hardened with a setuid helper binary, scoping NET_RAW to a minimal process instead of the full Python runtime.
• Smokeping integration disabled by default for new installs (existing configs are preserved).

Additional Changes

• Visual feedback (toast) on settings save actions.
• Connection Monitor added to README features table.
• Internal design docs excluded from repository.
