Build menu: hover popup with full info, top-left card hidden while building

The short description row became a status row for the selected piece
(variant, Replace, ghosts, messages). Gamepad shows the selected tile's popup.

## 2026-10-23: build menu hover popup, top-left card hidden while building (Claude Code, with Codex)
Notes: "mouse hover reviels a new info popup…" and "dont need the short description in the build
menu…". The owner chose to hide the top-left card entirely while building.
- `src/ui/build-menu.js`: `#bb-pop` above the hovered tile (icon, name, cost, size, power, full
description, how to place, filter help, build keys), clamped to the window; on a gamepad it
shows for the selected tile. The `.bb-tip` row became `.bb-status`: variant (material,
direction, filter) chips, Replace · Ctrl, ghosts waiting, and status messages. The bar now
updates its parts separately so hovering doesn't rebuild the tiles.
- `src/ui/selection.js`: `#selcard` is hidden for the build tool unless copying, cutting or
pasting; the build branch moved to the bar. `src/styles/style.css`: popup and status styles;
on narrow screens the bottom-right panel moves up while building.
- `src/ui/notebook.js`, `docs/DESIGN.md`, `docs/PROJECT_MAP.md`.
- Tests: `play.py` 118 checks (popup on hover, switching tiles, hidden on leave, gamepad,
no `.bb-tip`, card hidden while building and back for tools 1 and 2, status in the bar; the
Ctrl replace check now reads the bar). All 11 headless suites pass. `t_smooth.py`'s
half-resolution check is still flaky under load (~4.8): 1 pass in 3 runs, as before.
- Screenshots in `shots/` (build-popup-*) at 1280×800 and 900×700 in both looks.
- Open: at 900px wide the bottom-left hover-info panel sits partly under the build bar.
