OSS-Fuzz Integration Request

### Background

Following the recent [CVE-2025-47436](https://orc.apache.org/security/CVE-2025-47436/) heap buffer overflow vulnerability discovery and fix, I would like to propose integrating Apache ORC with the [OSS-Fuzz project](https://github.com/google/oss-fuzz) to help identify potential security vulnerabilities earlier through continuous fuzzing.

### Apache Projects Already Using OSS-Fuzz

Many Apache Software Foundation projects are already integrated with OSS-Fuzz, including:

- apache-axis2
- apache-commons-bcel
- apache-commons-beanutils
- apache-commons-cli
- apache-commons-codec
- apache-commons-collections
- apache-commons-compress
- apache-commons-configuration
- apache-commons-csv
- apache-commons-fileupload
- apache-commons-geometry
- apache-commons-imaging
- apache-commons-io
- apache-commons-jxpath
- apache-commons-lang
- apache-commons-logging
- apache-commons-math
- apache-commons-net
- apache-commons-text
- apache-commons-validator
- apache-cxf
- apache-doris
- apache-felix-dev
- apache-httpd
- apache-logging-log4cxx
- apache-poi
### Integration

I would prepare a pull request that adds:

1. Fuzzing harness to the Apache ORC repository
2. Integration configuration for the OSS-Fuzz project
3. Build scripts and related components

This proposal was previously discussed via email with @dongjoon-hyun, who suggested opening this issue for formal documentation before proceeding with the integration work.

I'm seeking formal approval from the Apache ORC PMC to proceed with the OSS-Fuzz integration. Once approved, I'll prepare the necessary pull requests for both the ORC and OSS-Fuzz repositories.

Thanks a lot!
