tmerritt 3ef16a6f99 Promote NES PowerPad Test Card (U) from _wip to top-level project
Moves NES PowerPad Test Card (U) from _wip/ to NES PowerPad Test Card (U)/ with full ROM build:
- Adds header.s, chr.s, linker.cfg (HEADER+PRG+CHR segments)
- Updates Makefile to build and verify reconstructed.nes vs rom.nes
- Adds rom.nes copy + copilot/rom.nes symlink per repo convention
- Verified byte-identical build

Pass 1 complete: full code/data classification (~7.2% code / ~92.8% data)
Pass 2 complete: routine headers for all ~50 labels, semantic naming for key
routines (Reset, NmiHandler, VramWrite, ReadPad, ProcessPads, etc.),
zero-page aliases in locals.inc (Zp00-Zp15)
Pass 3 complete: data tables named (PaletteData at ,
PadBitTableLives at )

Root OVERVIEW.md updated:
- Removes NES PowerPad Test Card from _wip skeleton table (21 → 20 skeletons)
- Adds NES PowerPad Test Card as #15 in numbered inventory (BYTE-IDENTICAL, Pass 2/3)
- Updates summary count from 14 to 15 projects
