Improve Bacalhau AEO and repair legacy documentation routes (#137)

## Summary
- define Bacalhau consistently as the Apache-2.0 open-source
compute-over-data project
- add answer-first documentation, metadata, structured data, and
LLM-readable resources
- repair 59 legacy documentation routes that currently land on 404 pages
- keep exactly one approved commercial relationship sentence on the
Bacalhau homepage
- remove other Expanso promotion and partner assets from Bacalhau
documentation

## Entity boundary
The only public Expanso relationship text in this repository is:
“Commercial support for Bacalhau is available through Expanso.”

## Validation
- TypeScript typecheck passes
- spell check passes
- Docusaurus production build passes
- generated sitemap contains 107 URLs
- generated internal targets and local redirect destinations were
checked successfully

+# Bacalhau v1.9.2 Release Notes
+
+Bacalhau v1.9.2 was released on July 19, 2026. This maintenance release improves execution error reporting and release reliability while updating core Go and Python dependencies.
+
+## Compute execution error propagation
+
+Errors reported by a compute execution are now propagated through the job execution path instead of being lost at the compute boundary. This gives operators and callers a clearer failure signal when a workload cannot complete successfully.
+
+## Release and dependency maintenance
+
+The release also:
+
+- hardens weekly release gates and tag creation;
+- consolidates weekly dependency updates;
+- updates the NATS Go client and Python client dependencies; and
+- improves compatibility for CI gateway tests.
+
+## Release artifacts and complete change history

 We are thrilled to announce the release of Bacalhau v1.7.0, marking a significant milestone in our journey to make distributed computing accessible and enterprise-ready. This release introduces enterprise support options, enhanced job management capabilities, significant performance improvements, and a host of new features that make it easier than ever for organizations to deploy and manage distributed compute networks at scale.
 
-### Enterprise Support through Expanso
+### Optional Commercial Support
 
-Bacalhau v1.7.0 introduces enterprise-grade support options through a flexible licensing model. Organizations can now purchase licenses for their on-premises Bacalhau networks. This offering ensures that enterprises have access to professional support, enabling them to confidently deploy and maintain their distributed compute infrastructure.
+Bacalhau v1.7.0 introduced license-handling features for optional commercial support offerings. The Bacalhau project and software remain open source under the Apache 2.0 license; any commercial license applies only to separately contracted support terms.
 
-Our tiered licensing model provides flexibility for organizations of all sizes, from growing startups to large enterprises, ensuring they receive the level of support that matches their needs.
+Optional support terms can be sized for organizations ranging from small teams to large enterprises without changing the open-source license for Bacalhau itself.

 #### Enterprise Support
 
-**Q: What license tiers are available?** A: Bacalhau offers a free tier supporting up to 5 nodes, making it easy for teams to get started. Beyond that, organizations can purchase licenses based on their node count requirements.
+**Q: What license tiers are available?** A: Bacalhau itself is open-source software under Apache 2.0. Optional commercial support terms are provided separately and may vary by node count.
 
 **Q: What happens if my network exceeds the licensed node count?** A: Your network will continue to operate normally even if you exceed your licensed node count. The system will display a friendly notice about the overage, giving you time to adjust your license as needed.
 
-**Q: How do I purchase a license?** A: Licenses can be purchased by contacting our sales team at [support@expanso.io](mailto:support@expanso.io).
+**Q: How do I purchase commercial support?** A: Use the commercial support link on the [Bacalhau home page](/) for the current contact path.
 
 **Q: How are licenses deployed?** A: Once a user receives their license, they can deploy it to their network. Only the orchestrator needs the license deployed, eliminating the need to manage licenses on compute nodes or clients. A new configuration option allows you to specify the local license path on the orchestrator.
