Pull Request Overview

This PR introduces a profiling/telemetry system to the Radar SDK to measure execution times of various operations during location tracking.

• Adds a new RadarTelemetry class for timing operations
• Integrates telemetry timing calls throughout the verification tracking flow
• Updates imports to be more explicit rather than using wildcard imports

File	Description
RadarTelemetry.kt	New telemetry class that tracks start/end times for operations and formats timing data
RadarVerificationManager.kt	Adds telemetry timing to track verification flow stages including config retrieval, location getting, integrity tokens, and API calls
Radar.kt	Integrates telemetry into the trackOnce method and replaces wildcard imports with explicit imports

Force unwrapping with !! could cause a crash if endTimes contains a tag that's not in startTimes. This could happen if end() is called without a corresponding start() call. Consider using safe access or validation.

Suggested change

	"${tag}: ${"%.2f".format(diff.toFloat() / 1000)}s"
	return endTimes.mapNotNull { (tag, endTime) ->
	val startTime = startTimes[tag]
	if (startTime != null) {
	val diff = endTime - startTime
	"${tag}: ${"%.2f".format(diff.toFloat() / 1000)}s"
	} else {
	null
	}

Using Date().time creates unnecessary Date objects. Consider using System.currentTimeMillis() which is more efficient for timing measurements.

Suggested change

	endTimes[tag] = Date().time
	class RadarTelemetry {
	private val startTimes: MutableMap<String, Long> = mutableMapOf()
	private val endTimes: MutableMap<String, Long> = mutableMapOf()
	fun start(tag: String = "") {
	startTimes[tag] = System.currentTimeMillis()
	}
	fun end(tag: String = "") {
	if (startTimes.containsKey(tag)) {
	endTimes[tag] = System.currentTimeMillis()

Public class lacks documentation. Consider adding KDoc to explain the purpose and usage of this telemetry class.

Suggested change

	/**
	* RadarTelemetry provides simple timing utilities for measuring the duration of code execution.
	*
	* Usage:
	* - Call [start] with an optional tag to begin timing.
	* - Call [end] with the same tag to end timing.
	* - Use [get] to retrieve the elapsed time in milliseconds for a tag.
	* - Use [formatted] to get a human-readable summary of all timings.
	*
	* This class is useful for performance monitoring and debugging.
