The executable builds to build/rogue. All generated artifacts go under
build/, which .gitignore covers as a whole; a target writing outside it
can commit its output.
build is in neither check nor test: check stays fmt-check lint test and
still writes nothing into the working tree.
README's "Building and running" block and the run examples use
./build/rogue, and no raw go invocation is left in the file.
Verified: make build writes build/rogue and git status stays clean;
GOFLAGS=-count=1 make check green in 34s with the lint layer executing
(21.9s, "0 issues.", not CACHED) and the suite running for real (cmd/rogue
1.027s, game 3.450s), git status clean afterwards.
Itemize the refactor from transliterated port to idiomatic Go: eight
stepped feature branches (descriptive constant renames, typed kind
enums, un-overloaded Object fields, per-subsystem method renames,
god-object extraction, effects dispatch tables, constructor/style
pass, docs refresh), slotted ahead of the existing playtest/lint/
release steps. Also add the styleguide-required .gitignore (a stray
built binary was sitting untracked in the root).
