Description

What type of enhancement is this?

Tech debt reduction

What does the enhancement do?

The vector index was introduced and tracked in #7668.

However, we do not believe that vector indexing is a core missing capability for GreptimeDB as an observability database, and we do not plan to continue investing in this area.

Therefore, we have decided to remove all code related to the vector_index feature, which has been gated behind a feature flag and disabled by default.

Contributor guide

Research direction
Search the repository for 'vector index' in source code, feature flags, tests, and configuration. Identify all code paths gated by the feature and remove them, including related tests and docs. Ensure no broken references remain and run the default build to verify.
