The repository had accumulated multiple, contradictory "current state" documents for V2 hardware: an old V1 IT/EN datasheet copy nested inside hardware/v2/docs/datasheet/, a stray untracked duplicate at repo root (docs/DatasheetLatex/), and a second, much older documentation track (hardware/v2/docs/*.md: PRE_PCB_VERIFICATION.md, PRE_PCB_CLOSURE_4POINT.md, MEMORY_UPGRADE_64MB_N8.md, and 10 more) describing an earlier PSRAM/ N_SLOTS<=2 milestone alongside the real, current SDRAM/N_SLOTS=4 board. The LaTeX datasheet's own front matter (features/pinout cover pages) and chapter 9 (benchmarks) were themselves still describing that obsolete architecture, contradicting the real, current chapters 5/7/10 elsewhere in the same document. This commit: - Flattens hardware/v2/docs/datasheet/files/docs/datasheet/v2-en/* up to hardware/v2/docs/datasheet/ (was 4 levels of redundant nesting). - Removes the old V1 IT/EN LaTeX copies and the stray root-level duplicate entirely (recoverable from git history, not from disk). - Preserves the real component reference PDFs (ECP5 eval board, ISSI PSRAM, programming cables) under datasheet/references/. - Removes 13 superseded hardware/v2/docs/*.md status documents after folding every real, unique fact they contained into the datasheet: SPI max verified clock (12MHz, exact 12.8MHz CDC edge), SDRAM directed boundary test (21/21 PASS), 16MHz oscillator MPN (ECS-3225MV-160-BN-TR), and the real FPGA<->SDRAM ball mapping cross-check. - Rewrites the datasheet's own front matter, ch.4 (parameters), ch.8 (top-level module -- was documenting the wrong, non-physical top entirely), and ch.9 (benchmarks) to describe the current, real SDRAM/ N_SLOTS=4 production board, while keeping the real PSRAM-era chapters as clearly-labeled history rather than deleting correctly-measured work. - Fixes a title-page tikzpicture that was clipped off the page edge (pre-existing, unrelated to this change) by scaling it to fit. Net: 85 files changed, -8814/+498 lines. hardware/v2/docs/ now contains exactly one current datasheet plus FIRST_POWER_ON.md (a bring-up runbook, not a duplicate spec).
