feat(hub): group Logs under Mods, demo mod self-repair, goto highlighting

- HubModsPages: register one 'Mods' top tab with [Mods, Logs] sub-tabs (HubSubTabPage)
  instead of two separate top tabs.
- Full Access demo: wire CoreAiLuaModAutoRepair into the demo Hub with the repair
  threshold lowered to one consecutive error, so a broken mod self-heals on first failure.
- LuaTokenizer: recognise the Lua 'goto' keyword so it highlights in the mod editor.

CoreAI.Mods.Tests 584/584 EditMode green; compile clean.
