cli: rename langgraph.json to langsmith.json

Browse Source 
Rename the default config filename from `langgraph.json` to
`langsmith.json` as part of the "LangGraph Platform" to "LangSmith
Deployment" rebranding.

Backward compatibility is preserved: the CLI falls back to
`langgraph.json` with a deprecation warning when `langsmith.json`
is not found. A new `_resolve_config` callback handles the
resolution logic for all `--config` click options.

Changes span libs/cli (core logic, examples, tests), libs/sdk-py
(docstrings), libs/langgraph (Makefile), and .github CI scripts.
