ChuckandClaude Opus 5.5 b3ce406ae6 Merge origin/main into claude/remove-skins-and-base-classes
Resolves the README.md / docs/CONFIG_REFERENCE.md conflicts with #607 (its
corrected text and function-name references, without the skins section; this
branch's use_short_date_format row), and drops the skin/skin_options entries
#607 documented in PLUGIN_CONFIG_CORE_PROPERTIES.md, since this branch retires
those keys.

## Contributing to the docs
- Markdown only, professional tone, minimal emoji.
- Prefer adding to an existing page over creating a new one. If you add a
new page, link it from this index in the section it belongs to.
- If a page becomes obsolete, delete it (it stays in the repository
history) and fix the links to it; `test/test_doc_links.py` fails on
broken relative links.
- Keep examples runnable — paths, commands, and config keys here should
match what's actually in the repo.
