- Replaced pass-by-value std::string parameters with const std::string& or std::string_view to prevent SSO overallocations. - Refactored static mapping functions in UPower to return std::string_view instead of constructing std::string literals, enabling perfect cache locality. - Optimized string concatenation in hot loops (network IPs, inhibitor lists, sway window marks) by using std::string::append() and pre-reserving capacity instead of overloaded operator+ which produces temporary heap instances. These optimizations reduce high-frequency memory churn and overall heap fragmentation within the main rendering loops. Signed-off-by: Austin Horstman <khaneliman12@gmail.com>
