Initialize shinyjson from shinychat with renames and hello world placeholders

[Copilot]

Bootstraps the shinyjson repo using posit-dev/shinychat as the template, renames all shinychat references to shinyjson, and strips business logic from R/Python/JS packages leaving minimal hello world placeholders.

Changes

Repository structure (from shinychat)

• Root: LICENSE, Makefile, pyproject.toml, .gitignore, shinyjson.Rproj
• .github/workflows/: R CMD check, pkgdown, py-check, py-release, quartodoc, verify-js-built
• js/: build toolchain (esbuild, eslint, tsconfig, package.json)
• pkg-py/: Python package scaffold
• pkg-r/: R package scaffold

Renames

All shinychat → shinyjson throughout file contents and filenames (package names, URLs, descriptions, Makefile targets, DESCRIPTION, pyproject.toml, NAMESPACE, etc.).

Business logic → hello world placeholders

R — all chat logic removed; single placeholder:

# pkg-r/R/hello_world.R
#' @export
hello_world <- function() {
  "Hello, World!"
}

Python — all _chat*.py removed; minimal package:

# pkg-py/src/shinyjson/__init__.py
def hello_world() -> str:
    """Return a Hello, World! greeting."""
    return "Hello, World!"

JavaScript — chat/markdown-stream/utils removed; single entry point:

// js/src/shinyjson/shinyjson.ts
export function helloWorld(): string {
  return "Hello, World!"
}

build.ts updated to reference src/shinyjson/shinyjson.{ts,scss} instead of the removed chat/markdown-stream entries.

Security

Added permissions: contents: read to verify-js-built.yaml to scope GITHUB_TOKEN to minimum required.

Original prompt

• Initialize the repo from https://github.com/posit-dev/shinychat
• Rename all occurrences of shinchat to shinyjson
• For the business logic in the R, python, and javascript folders... remove all of the logic files, but leave a "hello world" files as a place holder
