Document the engine's design decisions
The README says what the project does; nothing said why any of it works the way it does. This adds design notes written to be read end to end: each section states the decision, the reasoning, and what it cost. docs/GUIDE.md is the readable source. docs/guide.html is the same material as a self-contained reading page for the project site — no webfonts, no scripts beyond a progress rail, so it also works saved to disk and opened offline. Covers the context budget allocator, the propose-and-referee world-state engine, the measured length-hint result, the memory bank's settled-action and cursor rules, the two coordinate systems behind the summarization bugs, the retry variant machinery, the egress fix, and the demo-key pinning. Closes with the measured numbers, the known limitations, and a pointer to the cleanup backlog in self-review.md.
