Module timestamp 

High-precision timestamp generation with zero syscall overhead.

This module provides monotonically increasing timestamps using the CPU’s Time Stamp Counter (TSC) on x86_64, avoiding syscalls in the hot path.

Design

• Uses quanta crate which calibrates against the system clock once at startup
• Subsequent reads use RDTSC instruction directly (no syscall)
• Each shard has its own TimestampGenerator to eliminate contention
• Monotonicity is guaranteed via atomic CAS operations
