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.

interactive / telnet_suboption

telnet_suboption

NAME

telnet_suboption - process telnet suboptions

SYNOPSIS

void telnet_suboption( string buffer );

DESCRIPTION

This apply is called on the interactive object with the parameter given
by the SE telnet suboption, for mudlib defined processing.   For  exam
ple, this allows for future support of terminal types.

The  first  byte  of  the  buffer  is  typically  a type descriptor, ie
TELOPT_TTYPE. The next byte is a procession option, such as TELQUAL_IS.
Following  this  is the type dependent data.  In the case of a terminal
type call, the data will be routed through through the  terminal_type()
apply instead.

Possible suboptions:

    #define TELQUAL_IS    0 // option is...
    #define TELQUAL_SEND  1 // send options
    #define TELQUAL_INFO  2 // ENVIRON: informational version of IS
    #define TELQUAL_REPLY 3 // AUTHENTICATION: client version of IS
    #define TELQUAL_NAME  4 // AUTHENTICATION: client version of IS
