⚡ Optimize Profile Mappings Loop to Avoid Value Copying

[arvarik]

💡 What: The optimization implemented

• Changed for _, prof := range profiles to for i := range profiles.
• Accessed elements directly via profiles[i] instead of the iteration variable.

🎯 Why: The performance problem it solves

• In Go, for _, val := range slice copies each element of the slice into val. For slices of large structs, this can lead to significant unnecessary CPU and memory overhead.

📊 Measured Improvement:

• Due to network restrictions in the environment preventing the download of dependencies, I was unable to run automated benchmarks. However, this is a well-known Go performance pattern that eliminates O(N) struct copies per call. Given that eero.Profile contains multiple fields and a slice of devices, avoiding this copy is a clear efficiency win.
