Alem Tuzlak 6a1fceb979 fix(showcase/ms-agent-python): commit real demo binaries (drop LFS pointers)

sample.png and sample.pdf in `public/demo-files/` were committed as
130-byte LFS pointer text files (caught by the repo-root
`.gitattributes` `*.png filter=lfs`). The Docker build runs in CI
without `git lfs pull`, so production ships the literal pointer text
— `multimodal-sample-buttons.tsx` detects the magic prefix and
refuses to send, surfacing as "Git LFS pointer, not the real asset"
when users click Try with sample image / PDF on production.

langgraph-python committed the raw binaries (different blob SHAs).
Matched MAF's blobs to LGP's exactly (10083-byte PNG, 2486-byte PDF)
via `git hash-object -w --no-filters` + `git update-index --cacheinfo`
to bypass the LFS smudge filter. Added a per-directory
`.gitattributes` that turns off `filter/diff/merge` on these two paths
so future checkouts don't re-smudge them back into pointer text.

Demo Files — Multimodal Demo

This directory bundles sample files referenced by the /demos/multimodal page.

Required files (must be committed as binaries; see .gitattributes at repo root):

sample.png — a small (< 50 KB) PNG that the "Try with sample image" button injects into the chat. A CopilotKit logo or other recognizable brand mark works well so the vision-capable agent has something to describe.
sample.pdf — a small (< 50 KB) one-page PDF that the "Try with sample PDF" button injects. The content must mention "CopilotKit" so E2E soft assertions hold (e.g. a one-page export of the CopilotKit quickstart).

The page at src/app/demos/multimodal/page.tsx fetches these via the public path (/demo-files/sample.png, /demo-files/sample.pdf), wraps the fetched blob in a File, and routes it through the same AttachmentsConfig.onUpload callback the paperclip button uses — so the sample path exercises the exact same queueing code as a real user upload.

If these files are missing, the demo page still renders but the sample buttons will surface a fetch error. The paperclip / drag-and-drop paths continue to work without them.
