Mason Daugherty 4108c0738c release(core): 1.4.7 (#38111) ...

Bumps `langchain-core` to `1.4.7` for the next patch release and updates
downstream minimum `langchain-core` requirements so package locks
resolve against the new core version.

This also refreshes the runnable snapshots that embed `lc_versions`
metadata so the version consistency check continues to validate
checked-in artifacts.

Validated with `python libs/core/scripts/check_version.py`, `uv lock
--check` across package lockfiles, and the core runnable tests that own
the updated snapshots with local LangSmith tracing env disabled.
