DCMA Failure Remediation

When Health Checker fails checks, remediate in P6, then re-export XER.

Check family	Typical P6 action
Missing pred/succ	Add logic; avoid open ends
High / negative float	Revisit constraints and calendars
Hard constraints	Prefer soft constraints / logic
Leads / SF	Remove leads; eliminate SF where possible
Invalid dates	Align status, actuals, remaining duration
