Press fleet: two Newbilt Duplex systems with an extruder per press, plus a Classic

The current plan (user decision, October 2026) replaces the 50/50 target
(two semi-automatic presses and two Pheenix AD12s) with an all-Newbilt
fleet of five presses: two Duplex systems in Newbilt's two-extruder
configuration (two HRP 12 presses, an extruder each, one hydraulic unit)
and one Classic fully automatic press.

- pressing-line.md: new "Current plan" section (fleet table, what it
  means, phasing from the Single 2.1 as the first half of system 1,
  re-quote questions); site requirements per Duplex system.
- scale.md: capacity table and basis (368 to 448 records/h, ~1.06 to 1.5M
  a year on two shifts, same range as before); pressing electrical row;
  steam and cooling flagged, not re-based: five presses draw ~750 to 900
  kg/h of steam and up to ~625 kW of cooling at Newbilt's per-press
  figures, against the 400 kg/h / 250 kW sized for one Duplex.
- total-investment.md: fleet change as an added-scope row (system 2
  ~230k-300k and the Classic ~290k-460k, estimates; -60k / -160k against
  the two blocks it replaces); headline unchanged until the re-base.
- roadmap items 4, 5 and 24, revenue model mature row, crane doc (the
  Classic's weight now decides 5 t or 3.2 t), vendor landscape (AD12 is
  the comparison for the Classic), README.
