feat(docs): add GitHub Pages site — immersive landing + MkDocs docs

- MkDocs Material site: a custom dark "firefly-in-the-dark" landing
  (overrides/home.html, firefly.css, firefly-constellation canvas) over the
  existing 28 docs, with search, light/dark and the violet brand theme.
- New Getting-Started pages (installation, quickstart, jupyter) and an in-site
  changelog that snippet-includes CHANGELOG.md.
- GitHub Actions (.github/workflows/docs.yml) builds with `--strict` and
  deploys to GitHub Pages on push to main.
- Fix cross-file and GitHub-style anchor links so `mkdocs build --strict`
  passes clean (architecture, agents, reasoning, pipeline, tutorial, changelog).
- Correct install instructions: the package is NOT published on PyPI. Replace
  every `pip install fireflyframework-agentic` with the curl installer /
  from-source (uv sync) — in the landing hero, the installation page, the
  architecture diagram label (+ its generator) and the README alt text; remove
  the PyPI social link.

One-time manual step to go live: Settings -> Pages -> Source: GitHub Actions.
