CodSpeed benchmarks were building with -O2, while all firmware targets (ESP8266, ESP32, LibreTiny) use -Os. This mismatch means the benchmarks cannot detect inlining regressions that affect real devices — GCC under -O2 inlines functions that -Os outlines due to its size-conscious cost model. Switch to -Os with -ffunction-sections/-fdata-sections for proper dead-code stripping (needed because -Os preserves references that -O2 optimizes away at compile time).
