Combine no-wrench and all-purchases goals

If pursuing No Manual Repairs on the same run, do not buy Sonnet's/Reaper's wrench before completing the main game. Finish shopping afterward and speak to each merchant again to check the purchase achievement.

Gathering enough spare parts to afford something is different from having it in inventory. Check stock and achievement updates after buying.

Coverage and unverified points

Added 32 progression/revisit stages, main collection tables, and 29 normal-layout lore reading points with entrance requirements. Lore 28's location, L24's regional landmark, all display differences, every passage/wall across 339 cells, enemy HP/attack frames, and lore text are not included.
Sources disagree on Quatern's chip/fragment reward thresholds, Lune's poem count, and the older area text's red-skull price. No fixed thresholds are asserted: finish dialogue after all 24 Power Cells, hear every poem, and use the dedicated shop price of 750 for the skull.
Separates 40 normal achievements from 8 additions and checks the 2 added stations in normal mode too. Added Corrupt's 16 relocations/23 temporary health points, spare-parts uses without merchants, a PC record's saving cost of 100, and Atom's 3 phases. All chips/cells/platform-specific costs in that mode, all modified trial HP, and no-hit procedures remain uncovered. The normal 28-chip list is not copied as a complete Corrupt list.
Competitor prose, translated full chapters, map layouts, game screens, and sprites are not reproduced. Internal verification distinguishes text readable in the public browser from originals that could not be obtained due to native 403 responses.
