[TASK][Timpani-n] Align task release times across nodes within 10 microseconds

[LGSI-KarumuriHari]

📝 Task Description

Ensure synchronized task activation across distributed nodes with ≤10μs alignment.

📋 Checklist

• Use synchronized time for task release calculation
• Implement hyperperiod boundary alignment
• Account for activation jitter
• Monitor actual activation alignment
• Log alignment violations
• Optimize activation path for minimal latency

📐 Implementation Guidelines

• Functional Requirement: FR-9.3.2 - Align task release times across nodes within 10 microseconds
• Component: timpani-n/Time Synchronization(Gptp)/Time Sync Manager
• Use gPTP-synchronized CLOCK_REALTIME for activation
• Calculate activation times based on hyperperiod start
• Minimize jitter in timer delivery (< 100μs)
• Coordinate activation with other nodes via shared time base

🧪 Testing Method

• Unit test: Verify activation time calculations
• Multi-node test: Measure activation alignment across nodes
• Jitter test: Measure activation timing variance
