thejayman77 ec82764bef Initial commit: retroDE_ps2 — first-of-its-kind PS2 GS FPGA core (DE25-Nano / Agilex 5)

RTL (GS rasterizer, EE core stub, platform bridge, LPDDR4B path), sim regression
(272 TBs), docs, and tooling. Copyrighted PS2 content (BIOS, game code, GS dumps,
and all dump-derived textures/traces) is excluded via .gitignore and stays local.

Contract Docs

These files define subsystem boundaries for retroDE_ps2.

Each contract should answer:

what the block owns,
what enters and exits the block,
what timing or ordering guarantees matter,
what is allowed to be stubbed early,
what must be true before software is expected to progress.

These are design contracts, not user documentation.

Contract maturity levels:

Draft: planning-first, expected to change.
Locked for Phase N: stable enough to implement against for that phase.

Current status:

All files in this folder are Draft.
Current contract set includes a dedicated interrupt-controller contract in intc.md to keep ownership explicit across EE-visible subsystems.
sio2_pad.md is a Ch233 recon contract — no RTL yet — sketching how the Ch222 HPS-side input latches will become a PS2-side sio2_input_stub with an IOP-readable pad-state register set in a future implementation chapter.
