Write the README and third-party notices

The README says what 8bitMyGoUI is, in English with a Chinese
summary, and shows the gallery home in Winter Night. It covers
install, a first window, the eight palettes, the dot, locale and
Reduce Motion, the gallery and web commands, the showcase URL and
the 500 components by category. The example was compiled and
clicked headlessly in its own module; a gallery test keeps the
counts true to the registry.

THIRD_PARTY_NOTICES.md lists what the native gallery and the
showcase link, from go list -deps, each license copied verbatim:
MyGo, Ark Pixel Font, rsc.io/qr, go-text/typesetting,
golang.org/x/image, purego and Go itself.

AGENTS.md records the gallery sweeps, the console-error rule,
the budget test and what follows a third failed review.

 - Behavior tests drive `ui.Tester` and assert values. Timed components take `pixel.Settings.Now` from a test clock. `Tester.Focused(label)` is also true when an ancestor holds the focus.
 - `gallery` checks every entry under every palette: only palette colors, whole dots. Demos that call `pixel.Scope`, and the home and entry pages, may show other palettes. `PIXEL_SHOTS=<dir> go test ./gallery -run TestInvariants` writes PNGs for visual review.

+- `gallery` also sweeps all demos: keys, typing, clicks and the wheel as a veil falls log nothing; a clock stepping back crashes nothing and shows no new negative number; every Tab stop has a name; every gallery word has glyphs; the README's counts match the registry.

The budget test logs first frame, p50 and p95 (Go's share plus the canvas blit) and the wasm's brotli bytes, and holds them to PRD §6.

 ## Review
 
-Each TASKS.md item is reviewed in a Herdr pane split to the right, by `codex --yolo -m gpt-6.1-sol -c model_reasoning_effort=high -c service_tier=fast`. At most three rounds. The reviewer reports defects against PRD and this file, ends with `VERDICT: PASS` or `VERDICT: FAIL`, and does not reject work for missing enhancements.

After a third FAIL, the coordinator fixes each defect, proves the fix red then green, and records both in TASKS.md.
