fix(build): remove chat-ui references from wheel build script

[Pouyanpi]

Description

The chat-ui directory was removed in #1734 (Chatbot UI replaced by Chainlit), but .github/scripts/build.sh still tried to copy it into the package before running poetry build, causing the publish workflow to fail with "cannot stat 'chat-ui'".

Drop the CHAT_UI_SRC/DST variables and the corresponding cp/rm lines so the wheel build only copies the still-existing examples directory.

Greptile Summary

This PR removes four dead lines from .github/scripts/build.sh that referenced the chat-ui directory deleted in #1734. With those lines gone, the publish workflow no longer fails on the missing chat-ui source; the only remaining side-effect (copying/removing examples) is unchanged.

Confidence Score: 5/5

Safe to merge — targeted removal of stale references with no functional risk.

Single-file, four-line deletion that removes references to a directory confirmed absent from the repo. No logic changes, no new code paths, and the CI run linked in the PR description confirms the fix works.

No files require special attention.
