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.

# error_handler
### NAME
error_handler - function in master object to handle errors
### SYNOPSIS
void error_handler( mapping error, int caught );
### DESCRIPTION
This function allows the mudlib to handle errors instead of the driver.
The contents of the 'error' mapping are:
([
"error" : string, // the error
"program" : string, // the program
"object" : object, // the current object
"line" : int, // the line number
"trace" : mapping* // a trace back
])
Each line of traceback is a mapping containing the following:
([
"function" : string, // the function name
"program" : string, // the program
"object" : object, // the object
"file" : string, // the file to which the line number refers
"line" : int // the line number
])
The 'caught' flag is 1 if the error was trapped by catch().
