feat(installer): richer disk picker (vendor, model, serial, type)

Replaces the bare `NAME SIZE` lsblk listing in select_disk with a
six-column table — NAME, SIZE, TYPE, VENDOR, MODEL, SERIAL — aligned
via column -t. TYPE is derived from ROTA + TRAN (NVMe / USB / SSD /
HDD). Empty vendor/model/serial fields render as `--` instead of
collapsing the alignment. Filters loop, ram, zram, sr devices.

Roadmap row moves to Shipped.

 ### Now (ready to pick up)
 
 - **Software-profile multi-select in the installer.** Carryover from the old TODO. Add a `gum choose --no-limit` step in `installer/install.sh` (between hardware and impermanence) for opt-in profiles (Dev, Gaming, Office, Media, …). Each profile maps to a list of `home.packages` and optional `nomarchy.system.*` toggles emitted into the generated `home.nix`/`system.nix`.
-- **Richer disk metadata.** Carryover from the old TODO. Replace the bare `lsblk` line in `select_disk` with `lsblk -O -J` parsed via `jq`, surfacing vendor, model, serial, and size in the picker.
 - **Menu cleanup of orphaned references.** Walk `features/scripts/utils/nomarchy-menu` (379 lines, 23 submenus) and either wire each menu item to a real script or replace the `case` arm with a stubbed `notify-send` until the script is ported. See Pillar 3 below.
 - **Form-factor → laptop preset auto-enable.** When the installer writes `nomarchy.system.formFactor = "laptop"`, also flip on a yet-to-be-built laptop preset (TLP, brightness keys, lid handling). The option exists; the preset module doesn't.
