- Replace signed coordinate round-trips with checked offset helpers
- Use From/try_from conversions and clamp helpers in the edit parser
- Isolate exact RNG, noise and day-fraction float casts in documented helpers
- Split long functions (validate, world creation, apply, state_json, tick_person)
- Pass run_sim shared state by reference and tidy remaining style lints
Simulation behaviour and RNG sequences are unchanged.

Starting values and tuning constants are now `pub const` items in a
single Rune file, config.rn, alongside the `person`, `rabbit` and `wolf`
behaviour functions. The behaviours read the constants directly. At
startup the server loads the file from SIM_CONFIG (default: config.rn),
reads and checks every constant, and test-runs each behaviour, so a bad
or missing value stops startup with an error that names it.
- Map width and height can now be configured and are stored in
snapshots.
- The UI's edit limits (max speed, stock, inventory, hunger, energy,
resource amounts) come from the config.
- The in-browser script editor now edits config.rn. Applied edits update
behaviours and tuning values immediately; map size, initial population
and calendar defaults apply on reset.
- The Docker image includes config.rn, and Compose mounts the
repository's copy read-only.
- Documents the config file and how it works in the README.
BREAKING CHANGE: src/behavior.rn has been removed; behaviours now live
in config.rn. The server will not start without a valid config file.
Snapshots no longer store the behaviour script: on restart, config.rn
from disk replaces any edits made in the browser editor.
