Moves `@openprose/prose-cli` from `cli/` to `tools/cli/` and seeds a
`tools/` convention at the repo root for shippable tooling published as
standalone artifacts. Package internals are unchanged — only paths
outside the package that hard-code the `cli/` segment were updated.
## What changed
- `git mv cli tools/cli` — package files render as 100%-similarity
renames, so `git log --follow` is preserved.
- `.github/workflows/cli-publish.yml`,
`.github/workflows/cli-release-check.yml`, and
`.github/workflows/cli-real-harness-smoke.yml`: every literal `cli/`
path (`paths:`, `working-directory:`, `cache-dependency-path:`,
artifact `path:`, and inline `node`/`bash` invocations) now points
at `tools/cli/`. `cli-skills-smoke.yml` had no `cli/` references and
is untouched.
- `tools/cli/package.json`: `repository.directory` and `homepage` flip
to `tools/cli` so the npm registry "Repository" link resolves.
- `README.md`: the badge nav, the prose-layout paragraph, and the repo
layout table now point at `tools/cli/`, plus a new `tools/` row
introducing the convention.
- `RELEASE.md`: cross-references to `cli/RELEASE.md` updated.
- `tools/cli/README.md`, `tools/cli/RELEASE.md`,
`tools/cli/POST_RELEASE_PLAYTEST.md`: public installer URL updated to
`https://raw.githubusercontent.com/openprose/prose/main/tools/cli/install.sh`.
