Feat/sunday sprint 2 (#15)

* Fix HF Gradio SDK build: drop editable requirements.

HF pip installs requirements.txt before copying the repo, so -e ./libs/*
paths fail. Load monorepo packages via sys.path in app.py instead.

Co-authored-by: Cursor <cursoragent@cursor.com>

* Skip llama-cpp-python on HF Space build.

Compiling llama-cpp-python blocks HF builds for 10+ minutes. The Space
uses transformers presets; lazy-import llama_cpp only when selected.

Co-authored-by: Cursor <cursoragent@cursor.com>

* Disable Gradio SSR on HF Space so app binds to 7860.

HF enables SSR by default; without a working Node proxy Gradio falls
back to port 7861 and the Space container crashes.

* css layout

* origin fix

* Use ?classic query param for Classic UI on HF Spaces.

Root-relative /classic links resolve to http://hf.space under the Hub
embed and trigger mixed-content errors. Studio links use ?classic; the
server redirects to a relative classic path on the same HTTPS origin.
