host_env: export SIG*, sysconf, CLOCK_*, unix socket names - #8790
Conversation
Re-export signal numbers, pathconf/sysconf names, clock ids, and the unix socket integers the VM still took from libc. Assisted-by: Claude
signal, posix pathconf/sysconf enums, time clock ids, and the shared socket pyattrs re-export host_env instead of libc. Assisted-by: Claude

Alias WinSock SD_* as SHUT_* so the shared pyattr names resolve. Re-export the rest of the libc socket integers the VM still took from `use libc as c`. Assisted-by: Claude
Module integer names come from host_env. Types and syscalls stay on libc / WinSock. Assisted-by: Claude
pyattrs now take those names from host_env. Keep only the syscall names the shared body still reads as c::. Assisted-by: Claude
