feat: make doc-kit friendly for newcomers

[avivkeller]

I'm adding:

• serve (Build + Serve + Watch)
• bootstrap (Detect things like package name, docs path, and create a project)
• install (Install a generator package based on it's name, e.g. doc-kit install web)

Hopefully then new consumers can just doc-kit bootstrap && doc-kit serve to get their projects up-and-running. wdyt?

PR Summary

Medium Risk
Broad CLI and configuration behavior changes affect how every project resolves defaults and presets; install/bootstrap invoke the local package manager via spawnSync, which is environment-dependent but not security-critical.

Overview
Adds bootstrap, install, and serve so new projects can run doc-kit bootstrap then doc-kit serve for config, docs folder, .gitignore, generator installs, live preview, and rebuild-on-change (--static serves existing output only).

Configuration now supports extends (package specifiers or relative paths) with merge order: CLI → config file → presets → defaults. Built-in defaults drop Node.js-specific repository, baseURL, and changelog fetching; @node-core/doc-kit/config restores nodejs.org branding and URL layouts. Beta, e2e, and CI configs extend that preset.

The html generator is the public built-in name (web remains a deprecated alias). React html defaults use generic {project} titles, neutral logos, and optional GitHub/edit UI when repository / editURL are unset. generate and serve share options via createConfigurationOptions().

Docs, Playwright e2e, and getting-started are updated to document the new flow and doc-kit serve instead of external static servers.

It appears that this part of the modification is redundant with #984.
