[website] Add consent-gated kapa.ai "Ask AI" widget to docs site (#3760)

Integrate the kapa.ai "Ask AI" assistant, modelled on the Apache Doris
integration and compliant with the ASF privacy policy for third-party
resources.

- Privacy: data-consent-required makes kapa show its own consent screen
  and withhold all data from its backend until the user explicitly
  consents (remembered per device); analytics cookies disabled.
- CSP: kapa + reCAPTCHA domains added to .htaccess CSP_PROJECT_DOMAINS,
  per kapa's official CSP guide.
- UI: navbar "Ask AI" pill (cyan -> violet) opens the widget via
  data-modal-override-open-selector; kapa's own floating button hidden.

What is Apache Fluss?

Apache Fluss is a streaming storage built for real-time analytics & AI which can serve as the real-time data layer for Lakehouse architectures.

It bridges the gap between data streaming and data Lakehouse by enabling low-latency, high-throughput data ingestion and processing while seamlessly integrating with popular compute engines like Apache Flink and Apache Spark, with StarRocks coming soon.

Fluss (German: river, pronounced /flus/) enables streaming data continuously converging, distributing and flowing into lakes, like a river 🌊

Features

  • Sub-Second Data Freshness: Continuous ingestion and immediate availability of data enable low-latency analytics and real-time decision-making at scale.
  • Streaming & Lakehouse Unification: Streaming-native storage with low-latency access on top of the lakehouse, using tables as a single abstraction to unify real-time and historical data across engines.
  • Columnar Streaming: Based on Apache Arrow it allows database primitives on data streams and techniques like column pruning and predicate pushdown. This ensures engines read only the data they need, minimizing I/O and network costs.
  • Compute–Storage Separation: Stream processors focus on pure computation while Fluss manages state and storage, with features like deduplication, partial updates, delta joins, and aggregation merge engines.
  • ML & AI–Ready Storage: A unified storage layer supporting row-based, columnar, vector, and multi-modal data, enabling real-time feature stores and a centralized data repository for ML and AI systems.
  • Changelogs & Decision Tracking: Built-in changelog generation provides an append-only history of state and decision evolution, enabling auditing, reproducibility, and deep system observability.

Building

Prerequisites for building Apache Fluss:

  • Unix-like environment (we use Linux, Mac OS X, Cygwin, WSL)
  • Git
  • Maven (we require version >= 3.8.6)
  • Java 11
git clone https://github.com/apache/fluss.git
cd fluss
./mvnw clean package -DskipTests

Apache Fluss is now installed in build-target. The build command uses Maven Wrapper (mvnw) which ensures the correct Maven version is used.

Contributing

Apache Fluss is open-source, and we’d love your help to keep it growing! Join the discussions, open issues if you find a bug or request features, contribute code and documentation, or help us improve the project in any way. All contributions are welcome!
