fix(dtach): wire resume menu into ~/.bashrc for non-login VS Code shells

VS Code Remote-SSH integrated terminals are non-login interactive shells:
they source ~/.bashrc but never ~/.profile, where the resume menu was wired
(login-scope, BDR-007). The auto-check therefore never fired in the user's
actual environment, even after install.sh.

Source dtach-router from bashrc-linux (every interactive shell) instead, and
turn install.sh's wire_dtach_profile() into unwire_dtach_profile(): it now
strips any stale ~/.profile block so a plain SSH login (which reads ~/.bashrc
via ~/.profile) does not prompt twice. README updated to match.

 9. On Linux, installs `etc/profile.d/disk-usage-warning.sh` to `/etc/profile.d/` (needs `sudo`) so each login warns when `/` or `/home` cross 85% usage.
 10. On Linux, installs **code-server** (VS Code in the browser) via its vendor script — skipped if already present — and enables the `code-server@$USER` systemd service.
 11. On Linux, sets up **RDP remote login** via `gnome-remote-desktop` (Wayland-native): installs the daemon + `openssl`, generates a self-signed TLS cert once, and prompts interactively for shared "gate" credentials (skipped when no terminal is attached, or already set). Disables `xrdp` if present; opens UFW port `3389` only when UFW is already active.
