Added

• cha calibrate command: auto-suggest thresholds from project statistics (P90/P95)
• cha calibrate --apply saves to .cha/calibration.toml, auto-applied by cha analyze
• Finding priority sorting: most severe issues shown first (severity × overshoot × compound)
• Short module names in all output formats (terminal/DSM/dot/mermaid)

Changed

• DSM output limited to top 25 modules by file count

Fixed

• Skip parent→child layer violations (reduces lvgl false positives 87→37)
