Restructure the README around what Horizon is, its status, how to build it
from your own copy of the game, and its parity table. The Java performance
pack material and the research lab notes move to docs/java-packs.md and
docs/research-lab.md. The target platform is stated generically instead of
naming a machine, the stale list of missing mobs is dropped in favour of the
audited table, and the legal notice follows Mojang's usage wording.

Add version-bound core, world data, geometry, generation and feature implementations with native client/server comparison tools and scoped evidence reports. Apply Horizon project branding.
Workspace tests, Clippy and 147 Python tests passed. Full 51-family survival and expanded provider comparisons are still running; complete gameplay parity and a playable Rust client remain unfinished. Private game artifacts and the isolated simple-block placement work are excluded.
