feat(understand): the takeoff workbook and pipe_takeoff (SECTION 27 opens)

write_workbook builds the user's takeoff workbook from a result: Metraj (rows
with direct, continuity and unassigned lengths split, the allowance as its
own column, routed / unroutable / grand totals), Ozet (by service, diameter
and room), Kontrol (unassigned diameters and unroutable runs with the
reason) and Metodoloji, generated from the result: sources, the length
source and why, the scale-check verdict with its statistics, the units,
every rule and tolerance, and every warning. Headers and sentences in
Turkish, English or Russian. CSV always, one file per sheet; XLSX with
openpyxl, otherwise the xlsx_write refusal naming the office extra while
the CSV files are still written.

pipe_takeoff reads the P&ID and the layout once each (take_snapshot),
computes in a worker thread and never modifies either drawing. Tagged plant
and analysis; the plant pack is the integration task's. Alias record in
English, Turkish and Russian. Inventory regenerated; README snapshot 242
tools (237 advertised); registry snapshot analysis: 13.
