Bumps the gomod group with 1 update: github.com/bufbuild/buf.

Updates github.com/bufbuild/buf from 1.67.0 to 1.68.2

Release notes

Sourced from github.com/bufbuild/buf's releases.

v1.68.2

• Fix build failures for modules with a vendored descriptor.proto.
• Fix LSP incorrectly reporting "edition '2024' not yet fully supported" errors.
• Fix CEL compilation error messages in buf lint to use the structured error API instead of parsing cel-go's text output.
• Add --debug-address flag to buf lsp serve to provide debug and profile support.

v1.68.1

• Revert the use of the new compiler report format and properly ungate Editions 2024 features.
• Fix absolute imports (leading-dot) marked unused in diagnostics.

v1.68.0

This release ports buf to our new Protobuf compiler, already used to power the Buf LSP. It uses a query-driven frontend and a new AST and intermediate representation, designed from the ground up to bring several improvements:

• Better diagnostics. The new compiler produces rich, structured diagnostic reports with precise source locations. It also catches issues that protoc misses, such as duplicate repeated modifiers.
• Editions 2024 support. Full support for Protobuf Editions 2024.
• Faster and more memory efficient. Designed for large workspaces, the new compiler uses less memory and compiles faster than the previous implementation.

This is a seamless upgrade for buf users: no changes are required, the output has been automatically updated to a new, richer diagnostics report.

---

• Use new compiler for build process and support Editions 2024 features.
• Add LSP document links for buf.yaml deps, buf.gen.yaml remote plugins and input modules, buf.policy.yaml name and BSR plugins, and buf.lock dep names, making each a clickable link to its BSR page.
• Add LSP code lenses for buf.yaml files to update all dependencies (buf.dep.updateAll) or check for available updates (buf.dep.checkUpdates).
• Improve shell completions for buf flags with fixed value sets and file/directory arguments.
• Add buf curl URL path shell completions (service and method names) via server reflection, --schema, or the local buf module.
• Add support for Edition 2024 syntax to buf format.
• Fix buf generate --clean deleting files from nested plugin output directories.
