Major restructure of the README:
- Removed the misleading 'Keine echten LLMs' line from the
'Was es bewusst NICHT kann' section (we now have full Ollama +
OpenRouter support with per-agent models).
- Added a Highlights table at the top with status badges.
- Reorganised Quickstart into 3 paths: rule-based, Ollama,
OpenRouter (was a single Ollama path with optional LLM).
- New 'Was fehlt gegenüber dem Original' section: clear comparison
table mapping each original feature to the Mini equivalent and
explaining why we skipped it.
- New 'Token-Spar-Design' section: token budgets, model cost
examples, explicit 0-cost path via Ollama.
- 'Tests' section updated: real test counts per file (was a
generic '50+' stat), 99 total, breakdown by file.
- 'Time Dilation' section reorganised and made the live-validated
observation the headline.
- LLM provider section split into Ollama (default) and OpenRouter
(opt-in), with a free-model tool-use table and a per-day cost
example.
- Architecture tree includes engine/time.py, .env.example,
tests/ and removes nothing.
- Security section moved up and split from 'Tests' cleanly.
- All anchors updated and TOC added at the top.
