feat(lua): install Lua meta types

[idursun]

This PR adds an experimental convenience feature for users who customise jjui with Lua scripts.

It introduces a new CLI command, jjui --install-lua-types, which installs a Lua type definition file into the user’s jjui config directory. That file is generated automatically from jjui’s intent metadata, so the exposed action and API surface stays in sync with the application rather than being maintained by hand.

The goal is to make Lua-based customisation easier in editors that support LuaLS by providing autocomplete and basic type information while writing config.lua and related scripts. This is intended as a lightweight quality-of-life improvement for people already using jjui’s Lua scripting support, rather than a new core workflow.

i already made my own .luarc.json before, and running --install-lua-types gives below:

resulting in ~/.config/jjui/.luarc.json exists but does not include ~/.config/jjui/types.lua

im thinking this is because of this line here. although i don't imagine most user probably don't have an existing one (and probably .luarc.json won't be updated often), for those who do like me, this skip on .luarc.json cuases workspace.library to not be updated

Yes, I thought we shouldn't touch the file if the user has already put something in place as they are very like to be power users and know what they are doing.

allOwners comes from actionsByOwner, which only contains owners that have actions directly attached, and seems like this is causing jjui.status and jjui.revisions.quick_search to be left out ?

seeing this two fields being undefined in my editor with lua lsp

Thanks! Good catch! I'll have a look at this.

I had implemented this a couple of weeks ago and then did a refactor of the code generator then rebased this on top of the latest changes. I assumed all is good because there was no conflict but seems like some things might be out of sync now.

i think this function returns something like bool, string

Yes, I'll update this. Thanks!
