Add shared translators in hermes_constants (Windows drive → /mnt, `\\wsl(.localhost|$)\`
UNC → POSIX, gated on is_wsl) and apply them at the gateway session-cwd boundary
so a Windows-host UI can hand the WSL backend a path it can actually chdir into.
De-dups the ACP adapter's private `_win_path_to_wsl` onto the shared helper and
extends it to the UNC spelling.
