* refactor: remove dead code and enable noUnusedLocals
- delete launcher/jimaku.ts and the launcher Args/config jimaku* fields
that only fed it (the SUBMINER_JIMAKU_* env vars had no effect)
- delete plugin/subminer/hover.lua; nothing has sent subminer-hover-token
since Overlay 2.0
- drop never-read anilist.characterDictionary.refreshTtlHours and
evictionPolicy (still hidden in the settings UI for old configs)
- drop unused root deps: eslint, @fontsource-variable/geist{,-mono}
(stats/ declares its own)
- delete the committed draft renderer-performance plan doc
- turn on noUnusedLocals for typecheck and remove what it surfaced,
including Windows focus-handoff values computed but never consumed
* docs(changes): add docs fragment and note retired hover messages
