The install target stays in this repo's Makefile only. sneak/vaultik
already has an install target with another meaning, and every repo
still gets script/install.
Tests: a repo's own script/update-policy stops the script, and a repo
whose only JavaScript source is a .js or .mjs file gets the JavaScript
style guide.
Model: opus-5-5
A listed file the repo lacks is now written whole, with no keep rule.
A prompts/NAME.md goes to docs/NAME.md unless the repo keeps it at
NAME.md, and any other file goes to its own path. A language's files
are skipped when git tracks no source file of that language.
A listed path git ignores now stops the script before it writes.
README bullets split into short sentences, and a false sentence about
template repos deleted.
Model: opus-5-5
script/install replaced any tracked script/install or
script/update-policy in the target, including a repo's own unrelated
script. It now stops when such a file has a line the canonical file
has never held. An older shared copy is still replaced.
The padded file in the self-replacement test is now an earlier
canonical version, so the new stop does not catch it.
Model: opus-5-5
script/install fetches the policy files from prompts over HTTP and
writes them into a repo, installing itself and script/update-policy
there. script/update-policy fetches the current script/install, runs
it on its own repo and commits without pushing. The file list and the
rules for keeping a repo's own entries move to script/install.
