talk-doc: generate an HTML doc site for a package.
talk-doc [package-root] [out-dir] [source-root] [display-name] [--core-source path] [--core-docs-base URL] [--only source-path ...]
Defaults: root ".", out dir "docs", source root "<root>/src", and the package manifest's name. The output directory must already exist. Every .tlk file becomes a module summary page, and every public top-level declaration receives a standalone reference page. A leading // WIP: marker adds work-in-progress status to the module index and its generated pages. A Core source catalog makes Core symbols linkable without rendering duplicate pages. --only still indexes every module but writes pages only for the listed source paths.
