P1 Badge Bump langchain-core with langchain

This new pin is installed by workflows that run pip install -r requirements.txt (for example .github/workflows/agents-auto-pilot.yml), but langchain 1.3.9's PyPI metadata requires langchain-core>=1.4.6 while requirements.txt still pins langchain-core==1.4.3 on the next line. In those installs pip has no satisfiable set, so agent/LLM jobs will fail before executing; bump the core pin and regenerate requirements.lock with the same change.

Useful? React with 👍 / 👎.

# - Do not pin `langchain-core` directly here; let the selected `langchain`
# release resolve a mutually compatible core version.

P2 Badge Keep the consumer template pin in sync

This file is an exact template-sync source (.github/sync-manifest.yml lines 213-215), and maint-68-sync-consumer-repos.yml copies consumer files from templates/consumer-repo, where templates/consumer-repo/tools/requirements-llm.txt still says langchain==1.3.4. With only the source changed, Health 72/validate_template_sync.py will flag drift and consumer sync PRs won't deliver the bumped LLM dependency; update the template copy in the same commit.

Useful? React with 👍 / 👎.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
