ship: bake pipeline — correlator as a tested module + viewer prefers captured table

Promote the F10 ship-capture correlator from an example into a reusable, unit-
tested library module (ship_capture): parse_capture (log -> per-draw rigid
WorldView from the c0..c2 WVP constants), correlate (match parts to draws by
vertex count, express each in the reference part's frame), and a checked-in
placement-table format (serialize_table/parse_table, embedded via
embedded_placement from data/ship_placements.txt).

build_ship_model now prefers a ship's captured placement over the static
assemble_ship when a table entry exists (empty table -> unchanged fallback).
correlate_capture example refactored onto the module + gains --emit to print a
table block. Doc updated: bake plumbing done; remaining is running real F10
captures to populate the table (needs the emulator).

5 new ship_capture tests (parse/normalize/correlate/table round-trip); 76
formats-lib tests + viewer build green.
