Subject: [PATCH 2/4] fix: migrate chainlit 1.x/langchain 1.x to chainlit
 2.x/langchain 2.x
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- chainlit Action API: value/description → payload/tooltip (bedrock.py)
- langchain imports: langchain.* → langchain_classic.* / langchain_text_splitters / langchain_community.vectorstores
- requirements.txt: add chainlit>=2.0.0, langchain-classic, langchain-text-splitters

Tested: chainlit run app/bedrock.py starts successfully with
  Python 3.12 + chainlit 2.9.6 + langchain-aws 1.3.1

Subject: [PATCH 3/4] fix: add langchain-classic, chainlit,
 langchain-text-splitters to requirements.txt

These packages are required for the langchain 2.x migration but were
missing from requirements.txt. langchain-classic is a PyPI package (v1.0.1)
that provides backward-compatible LLMChain, PromptTemplate, etc.

Subject: [PATCH 4/4] fix: defer chainlit.context import to avoid
 lazify/pydantic conflict

lazify 0.4.0 + chainlit 2.x causes ChainlitContextException when
pydantic builds Chain subclasses at module load time. Moving the
chainlit.context import inside the point_camera_to_entity() function
prevents the eager evaluation and resolves the import-time error.

Closes: ChainlitContextException on module import
