security: strip debug symbols from release builds

[hongkongkiwi]

Summary

Strip debug symbols from release builds to reduce binary size and improve security.

Changes

• Changed debug = 1 to strip = "symbols" in [profile.release] section of Cargo.toml

Security Impact

• Reduces binary size
• Removes debug information that could aid reverse engineering
• Makes debugging production crashes slightly harder (but production should use crash reporting tools)

Thanks for the PR @hongkongkiwi

I need additional details to understand how this change improves security.

Yes, removing the debug reduces the binary size. But its a choice and not a security issue. And if anyone wants less size, they could build by themselves.

As for the reverse engineering part, Lightway source code is completely open source. What does the adversary have to reverse engineer ?
