T
D4rkst3randClaude Opus 5 a33dba46a4 FiveM Natives + Docs Nachschlagewerk 
7359 Natives (GTA5 + Cfx) und 342 Doc-Seiten von docs.fivem.net in einer
SQLite-DB mit FTS5-Volltextsuche, dazu ein dependency-freies Python-CLI und
eine SKILL.md fuer Claude Code.

- build.py zieht runtime.fivem.net/doc/natives*.json und citizenfx/fivem-docs
  und loest die Hugo-Shortcodes der Docs auf (code, native_link, alert, events)
- lua_name folgt exakt der Regel aus FiveM ext/natives/codegen_out_lua.lua
- fivem.py: show / search / ns / docs / doc / stats, optional --json
- data/natives.jsonl als grep-barer Fallback
