"Biome" describes per-zone vegetation classification (Whittaker table).
"Planet class" describes overall planetary character. The conflation
caused the planet generator to misclassify ~270 bodies as barren.
Scope: systems.db column, schema SQL, Rust atlas code, wiki table
headers (Biome → Class), atlas proposal JSONs, all docs/decisions,
tooling scripts. Also normalizes atmosphere vocabulary (breathable →
standard) and expands planet class mapping to all 26 wiki values.
Unknown classes default to temperate for modder safety.

The refactor from &Commands to individual parameters exposed the
13-argument signature to clippy. Allow attribute is appropriate
here — the parameters map 1:1 to DB columns.

Extract 2119-line monolithic atlas.rs into 8 focused modules under
src/bin/atlas/: main.rs (thin dispatch), common.rs (shared types and
DB helpers), show.rs, mutate.rs, stats.rs, systems.rs, author.rs,
and sync_wiki.rs. Commands enum stays in main.rs; each match arm
delegates to module::cmd_fn(&conn, args). No behavior change.
Closes#776.
