sneak 118f8e22c3 Add failing tests for the project name and build context
script/projectname still prints the pre-rename name, so make docker tags
its image quack, and .dockerignore has drifted from .gitignore: a compiled
bin/quak, the vitest and tsc caches, the CLI's runtime directory and the
local worktree directory all reach the build context. Neither failure is
visible in a build that exits 0.

Red until the fixes land.

// The Docker build context is load-bearing in two directions, and both
// failures are silent.
//
// Excluding too little: a worktree left under `.claude/` is copied into the
// image, vitest globs its `test/` tree as well as the real one, and the
// containerised `make check` runs the whole suite twice over while reporting
// success. A compiled `bin/quak` is ~100 MB of context nobody needs.
//
// Excluding too much: Prettier 3 reads `.gitignore` as a default ignore file,
// so dropping it from the context silently changes which files
// `make fmt-check` looks at inside the image compared to the host.
//
// Neither shows up as a build failure, so they are asserted here.
