- Add writeAllocsProfile() helper in pprof_impl.go
- Register /allocs route in PprofHandler.ServeHTTP
- Add handleAllocs() method with proper streaming response
- Update index page to list the new allocs profile link
This aligns lolly's pprof endpoints with net/http/pprof and enables
allocation hotspot analysis during performance benchmarking.
Conflict: sendfile.go (!linux build tag) was incorrectly modified to
include linuxSendfile and getSocketFd functions which already exist
in sendfile_linux.go.
Resolution: Keep HEAD version (simple fallback returning ENOTSUP) as
Linux implementation is properly separated in sendfile_linux.go.
