Go 1.26

Go 1.26 introduces a generational garbage collector, significantly faster cgo calls, an experimental SIMD package, and targeted language improvements.

• Generational garbage collector — internally redesigned GC reduces p99 pause times by up to 40% under high allocation rates; the GOGC tuning API is unchanged
• Cgo calls 30% faster — runtime restructured to reduce Go/C boundary overhead; database drivers, graphics bindings, and syscall wrappers benefit the most
• Experimental SIMD package — enable GOEXPERIMENT=simd at build time for the new simd/archsimd package exposing hardware-accelerated vector ops on x86-64 and ARM64
• new() accepts expressions — removes the need for temporary variables created solely for taking their address
• Heap base address randomisation — 64-bit platforms now randomise heap base addresses, raising the bar for memory-corruption exploits
