refactor: trim PR debloat and fix transformers build

Extract shared helpers for home notices, timetable subtitles, and theme images; dedupe global search, Select, and build scripts while preserving behaviour.

Add @huggingface/transformers as a direct dependency and resolve ORT WASM paths via require.resolve so pnpm postinstall and Vite can bundle vector search.
