blog process to add authors et all

Description

Converts the documentation build from zensical back to mkdocs-material and
cleans up the blog and docs CI:

• Build: zensical build/serve → mkdocs build/serve in the Makefiles and
  CI action; drop the zensical dependency and the mkdocs_badges.zensical
  markdown extension (the badges mkdocs plugin provides the same rendering).
  This also aligns the local/artifact build with what mike deploy has been
  publishing all along.
• Blog: let the Material blog plugin generate the index, archive, and
  category pages instead of hand-written listings; add post authors via
  docs/blog/.authors.yml.
• Navigation: expand sidebar sections by default (navigation.expand).
• CI: e2s-docs-light now only runs when docs content (including blog
  posts), examples/recipes, the docs toolchain, or the pipeline itself
  changes — other pushes skip the H100 docs rebuild (workflow_dispatch
  still forces one, e.g. after docstring-only changes).
• Lint: add a codespell pre-commit hook over hand-written docs
  (README, mkdocs.yml, non-generated docs/**/*.md) and wire it into
  make lint.

Verified: make docs end-to-end, uv lock --check, badge autosummary/filter
rendering, blog author rendering, sitemap, and mike compatibility.

Known follow-up: docs/blog/archive.md, docs/blog/categories.md, and
docs/blog/categories/documentation.md are now orphaned duplicates of the
plugin-generated pages and should be deleted.

Greptile Summary

Converts documentation builds from Zensical back to MkDocs Material and simplifies blog generation, while narrowing automatic light-doc rebuilds and adding documentation spell-checking.

• Replaces Zensical build and serve commands with MkDocs.
• Lets the Material blog plugin generate blog listings, archives, and categories.
• Adds blog author metadata and expanded navigation.
• Adds path filtering for light-doc deployments and a codespell pre-commit hook.
• Removes the Zensical dependency and corresponding lock entries.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete blocking or independently actionable non-blocking defects identified.

The MkDocs migration, blog metadata, lint integration, and dependency cleanup are internally aligned, while the intentionally deferred source-only deployments and orphaned blog pages are already documented by the author.
