Promote NES PowerPad Test Card (U) from _wip to top-level project

Browse Source 
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

## Skeleton Projects (under `_wip/`)
21 additional ROMs awaiting full disassembly. Each is set up as a Pass-0 skeleton (`default_project.tar.gz`): `copilot/` contains the split `prg.bin`/`header.bin`/`chr.bin`, a symbolic skeleton `prg.s`, and builds **BYTE-IDENTICAL** at the PRG level. Mapper 0 / 16 KB PRG / 8 KB CHR for all.

- **Pac-Man (U)** RESET at `$FF00` (vector-page tail), while the Tengen variant RESETs at `$C033` — different builds confirmed (PRG bytes differ).
- **MUSCLE (U)** vectors sit in the `$8000-EFFF` window — inconsistent with the `prg.s` skeleton's expected `$C000-$FFFF` mapping; verify the header/image match before Pass 1.
- **Lunar Pool (U)** NMI `$FF65` / IRQ `$FF64` are adjacent in the vector page; RESET `$E80C`.
- **NES PowerPad Test Card (U)** RESET/IRQ both at `$E000`, far from the usual `$C000`-page entries.
- **NES PowerPad Test Card (U)** — *at Pass 2/3*: minimal code (~7.2%), data-heavy test cartridge. RESET at $E000 (non-$C000 entry). NMI handler reads controllers via shift register, processes pad transitions, draws score/lives. See `NES PowerPad Test Card (U)/OVERVIEW.md`.
- **Ice Climber (JE) vs (U)**: byte-identical PRG *and* header — only the CHR differs (~regional title graphic).
- **Popeye (JU) PRG 0 vs PRG 1**: different PRG binaries (and mirroring); same vectors.
- **Raid on Bungeling Bay (U) vs [a2]**: `[a2]` differs in mirroring only per header, but PRGs differ — separate builds.

Every project builds successfully with `make` in the `copilot/` folder, and every reconstructed ROM matches the original byte-for-byte. Donkey Kong Jr. shares the same byte-identical build guarantee; its remaining Pass 2/3 work is semantic renaming and table decoding, not build-correctness.

The 21 `_wip/` skeleton projects above also all rebuild byte-identical (PRG level); all Pass 1 work and promotion to this index's numbered inventory is future work.
