Add local search and documentation guide for docs site (#1221)
* docs: add local full-text search and a contributor README

Add @easyops-cn/docusaurus-search-local to the Docusaurus site so the
docs get an offline search bar (index built at build time, no external
service). English and zh-CN pages are both indexed, and matched terms
are highlighted on the target page.

Add docs/README.md describing the Docusaurus setup, local dev/build
commands, search behavior, directory layout, and gotchas; exclude it
from the published site alongside CLAUDE.md. Point the root README's
docs/ entry at it.

* docs: remove dead framework leftovers, fix index generation, complete the nav

Delete the VitePress (.vitepress/) and Jekyll (_layouts/, css/) leftovers,
the one-shot migration scripts (fix_md_header.py, fix_seealso.py), and the
stale keywords.json snapshot; prune the matching .gitignore entries and
docusaurus exclude patterns.

Rewrite gen_index.py for Docusaurus: it emitted dead .html links and
legacy 'layout: doc' frontmatter, choked on non-markdown entries, and
dropped nested categories — regenerating an index would have broken it.
It now emits the extension-less links the site actually uses, links
nested category indexes (restoring apply/* on the zh-CN index), and
refuses to run on the docs root. Fix update_index.sh's copy-paste titles
(zh-CN efun/build were titled 'APPLY'), stop it clobbering the
hand-written lpc/index.md, and cover cli/. Regenerated indexes pick up
the missing driver/ffi-plan entry. add_missing_efuns.py now takes the
keywords.json path as an argument instead of requiring a stale copy.

Move CNAME and the Google site-verification file into static/ so they
actually reach the published build output.

Complete the sidebar: link the CLI category to cli/index and add the
missing portbind/symbol/generate_keywords pages, and expose the
previously orphaned stdlib section under Reference.

Promote onBrokenLinks to 'throw' now the build is warning-free, and drop
the empty Demo section from the landing page.

* docs: strip legacy 'layout: doc' frontmatter from all pages

Mechanical sweep removing the Jekyll-era 'layout: doc' line from every
doc page's frontmatter (Docusaurus ignores it), and the matching line
from the templates in docs/CLAUDE.md so new pages don't reintroduce it.
No content changes.

OOP stands for "Object-Oriented Programming".

If you know how to code in C or Pascal or even one of the modern BASICs (with procedures), then you already have many of the skills you will need to program effectively in LPC. The main thing you need is a skill in translating your ideas into a sequential flow of steps (that a computer can perform). However, LPC is also an object-oriented language. To effectively use LPC, you would benefit from a knowledge of OOP principles and concepts. Following are some of the principles of object-oriented programming (note that LPC doesn't necessarily provide mechanisms supporting all of these principles):

  1. systems are modularized on the basis of their data structures.

  2. objects should be described as implementations of abstract data types.

  3. unused objects should be deallocated by the underlying language system, without programmer intervention.

  4. every non-simple type is a module, and every high-level module is a type.

  5. a class may be defined as an extension or restriction of another.

  6. program entities should be allowed to refer to objects of more than one class, and operations should be permitted to have different realizations in different classes.

  7. it should be possible to declare a class as heir to more than one class, and more than once to the same class.

[These seven principles were taken from the "Object-oriented Software Construction" book by Bertrand Meyer]
