Jeffrey Wilcke 3c75674489 docs: README, dead-code cleanup, smoke fixes
- README with run instructions and key reference
- lift the crate-level dead_code allowance; scope it to the anim library surface
- render paths tolerate a city that is still generating (district/building ids
  without entries), found by driving the app through a pty
- status messages show in the status bar, not only inside the inspector
- buffered JSON export (26 s -> 0.4 s for a large city)

cyberpunk

A terminal game in a full cyberpunk setting. This is the first piece: a seeded, deterministic city generator and the full-screen terminal app around it.

The generator builds a multi-level city as walkable tile maps on four strata:

Stratum What lives there
Heights rooftops of the tall towers, helipads, bridges between them
Skyways elevated walkways, mid-rise lobbies, platforms over intersections
Street districts, arterials, blocks, buildings, markets, neon
Undercity tunnels under the roads, sewers, a rail line, basements, black clinics

Every building you see at street level is the same building you stand on at Heights. Districts have themes (corp core, night market, megablocks, combat zone, docks, industrial, neon strip, old town) that drive street layout, building mix, palette and signage. A Net graph of subnets, nodes and links is anchored to the physical tiles and can be shown as a digital overlay.

Same seed and parameters always produce a byte-identical city.

Run

cargo run --release -p city

Headless generation, for scripts and the game later:

cargo run --release -p city -- gen --seed 42 --size medium --out cities/demo.city
cargo run --release -p city -- gen --seed 42 --size large --json --out /tmp/demo.json

Sizes: small (160x80), medium (240x120), large (320x160) or WxH. Other flags: --districts 4..12, --water none|bay|river, --density 0..1.

Needs a truecolor terminal of at least 100x30 cells (iTerm2, Ghostty, kitty, WezTerm). Saved cities go to ./cities/*.city.
