feat(git): deploy user-scope ~/.gitconfig from the repo template

Browse Source 
Git never expands $VARS in its config, so gitconfig carries @USER@ and
@EMAIL@ placeholders that install.sh fills from the deployed bashrc's
USER/EMAIL exports. A differing ~/.gitconfig is kept as
~/.gitconfig.backup-<date>; an identical one is left alone. A repo's
.git/config still overrides it. excludesfile uses ~ (git expands it,
not $HOME).

The rc files now override $USER, so the installer takes the login name
from id -un for dscl and the code-server unit.

3. Moves any existing `~/.vim`, `~/.vimrc`, `~/.bashrc`, `~/.Sublivim` to `~/Oldconfig`.
4. Clones the `syntastic` and `nerdtree` vim plugins into `~/.vim/bundle/`.
5. Copies the tracked vim files into `~/.vim` and symlinks `~/.vimrc`.
6. Picks the bashrc by OS: macOS → `bashrc-osx` (falls back to `bashrc-linux` if missing), everything else → `bashrc-linux`. Copies it to `~/.bashrc`.
6. Picks the bashrc by OS: macOS → `bashrc-osx` (falls back to `bashrc-linux` if missing), everything else → `bashrc-linux`. Copies it to `~/.bashrc`. Then renders `gitconfig` into `~/.gitconfig` with that bashrc's `USER` / `EMAIL`. A different existing `~/.gitconfig` is saved as `~/.gitconfig.backup-<date>`; an identical one is left alone. It is the global level only: a repo's own `.git/config` still overrides it. `core.excludesfile` points at `~/.gitignore`, ignored by git when the file does not exist.
7. Installs Python CLIs via `pipx` (`PyMuPDF` → `pymupdf`, `Markdown` → `markdown_py`) — skipped if `pipx` is absent.
8. Copies the `bin/` scripts (`dt`, `dtach-router`, `claude-provider`) into `~/.local/bin`. The dtach session-resume menu ships in the deployed bashrc (both OSes), so every interactive shell offers it — including VS Code Remote-SSH terminals, which are non-login and never read `~/.profile`. The installer also strips any older dtach block left in `~/.profile` so a plain SSH login doesn't prompt twice.
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@$USER` systemd service.
10. On Linux, installs **code-server** (VS Code in the browser) via its vendor script — skipped if already present — and enables the `code-server@<login>` systemd service (login from `id -un`: the bashrc overrides `$USER`).
11. On Linux, installs **`ubuntu-desktop-minimal`** (GDM + GNOME Shell, ~1.5 GB): the RDP remote login below hands out a GNOME session, which a bare server install does not have. Then 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. Finally, when `lspci` sees an NVIDIA GPU, runs `ubuntu-drivers install` to put on the driver the distro recommends for the card (no version pinned; loads at the next reboot). Skipped on machines without an NVIDIA GPU.
12. On Linux, installs the **`cloudpex`** NAS mount helper to `/usr/local/bin` via `cloudpex/install.sh`, which prompts for the NAS host, share name, SMB user, mount point and SMB version and writes them to `/etc/cloudpex.conf` (root, `0600`; an existing config is shown and kept unless you say `n`; skipped when no terminal is attached). Nothing is mounted, no password stored, see [`cloudpex/README.md`](cloudpex/README.md).
13. On Linux, installs the **security baseline**, always, no prompt: **fail2ban** (+ `nftables`) with `etc/fail2ban/jail.d/local.conf` (sshd jail reading the journal, bans the offending IP on every port so the SSH port does not matter, 5 failures in 10 min → 1 h ban, loopback and private LAN ranges never banned); **unattended-upgrades** enabled through `etc/apt/apt.conf.d/20auto-upgrades`; and the **sshd drop-in** `etc/ssh/sshd_config.d/20-hardening.conf` (`PermitRootLogin no`, `MaxAuthTries 3`, `LoginGraceTime 20`), checked with `sshd -t` and removed again if sshd rejects it, then `reload ssh`. Authentication methods, port and user lists are left as they are.
