- **Description:** Aerospike Vector Store has been retired. It is no
longer supported so It should no longer be documented on the Langchain
site.
- **Add tests and docs**: Removes docs for retired Aerospike vector
store.
- **Lint and test**: NA
Added a short section to the Weaviate integration docs showing how to
connect to an existing collection (reuse an index) with
`WeaviateVectorStore`. This helps clarify required parameters
(`index_name`, `text_key`) when loading a pre-existing store, which was
previously missing.

Description:
Added the content= keyword when creating SystemMessage and HumanMessage
in the messages list, making it consistent with the API reference.
### Summary
This PR updates the sentence on the "How-to guides" landing page to
replace smart (curly) quotes with straight quotes in the phrase:
> "How do I...?"
### Why This Change?
- Ensures formatting consistency across documentation
- Avoids encoding or rendering issues with smart quotes
- Matches standard Markdown and inline code formatting
This is a small change, but improves clarity and polish on a key landing
page.
Change "Linkedin" to "LinkedIn" to be consistent with LinkedIn's
spelling.

- **Description:** Updated Docker command to use ClickHouse 25.7 (has
`vector_similarity` index support). Added `CLICKHOUSE_SKIP_USER_SETUP=1`
env param to [bypass default user
setup](https://clickhouse.com/docs/install/docker#managing-default-user)
and allow external network access. There was also a bug where if you try
to access results using `similarity_search_with_relevance_scores`, they
need to unpacked first.
- **Issue:** Fixes#32094 if someone following tutorial with default
Clickhouse configurations.

Supersedes #32544
Changes to the `trimmer` behavior resulted in the call `"What math
problem was asked?"` to no longer see the relevant query due to the
number of the queries' tokens. Adjusted to not trigger trimming the
relevant part of the message history. Also, add print to the trimmer to
increase observability on what is leaving the context window.
Add note to trimming tut & format links as inline

mistakenly used instead of `"gpt-oss"`.
