Re-vendor the shared files from sneak/prompts at dd4027b (closes #504)

Fetches the shared files unchanged from sneak/prompts commit dd4027b and
adds .prettierignore; .dockerignore keeps this repository's anchored host
artifacts at its end.

Linting moves into the Dockerfile's lint phase on the golangci-lint
v2.14.0 image, which also runs the js-lint stage, and Dockerfile.lint is
gone. Tests move into a test phase on the golang bookworm image.
script/lint, test, docker and cibuild are the model scripts, every docker
build in script/ passes --no-cache, and the .ci-fingerprint barrier is
gone. The workflow no longer calls script/ci-mark-superseded, so it and
its tests are removed. make build passes -trimpath and -s -w.
