This upgrade brings several performance improvements and bug fixes:

#### Performance improvements
- remote execution: bazelbuild/bazel#27564
- module extensions: bazelbuild/bazel#27296

#### Reliability improvements
- cache invalidation: bazelbuild/bazel#27417
- configuration: bazelbuild/bazel#27128
- Git repositories: bazelbuild/bazel#27705
- query:
  - bazelbuild/bazel#27560
  - bazelbuild/bazel#27117
- registry mirrors: bazelbuild/bazel#27531

#### Bug fixes
- remote cache: bazelbuild/bazel#27996
- repository handling: bazelbuild/bazel#27995
- repository cache: bazelbuild/bazel#28161
- local execution: bazelbuild/bazel#27994

This upgrade brings several performance improvements and bug fixes:

## Performance improvements (8.5.0)
- Remote execution: Add --remote_max_concurrency_per_connection flag to control concurrent gRPC requests (default: 100)
  bazelbuild/bazel#27564
- Module extensions: Support storing/retrieving JSON-like Starlark objects without invalidation, reducing unnecessary rebuilds
  bazelbuild/bazel#27296

## Reliability improvements (8.5.0)
- Cache invalidation: Source directory contents now tracked for proper invalidation
  bazelbuild/bazel#27417
- Configuration: Add ctx.configuration.short_id for identifying configurations
  bazelbuild/bazel#27128
- Git repositories: git_repository now checks out default branch when unspecified
  bazelbuild/bazel#27705
- Query: Add executables() function and fix genquery for external repos
  bazelbuild/bazel#27560
  bazelbuild/bazel#27117
- Registry mirrors: --module_mirrors now supports per-registry mirror specification
  bazelbuild/bazel#27531

## Bug fixes (8.5.1)
- Remote cache: Add option to continue with local execution if remote cache is unavailable
  bazelbuild/bazel#27996
- Repository handling: Fix crash when mixing use_repo_rule and --inject_repository
  bazelbuild/bazel#27995
- Repository cache: Fix permission denied issue with --experimental_repository_cache_hardlinks
  bazelbuild/bazel#28161
- Local execution: Fix incorrect SkyframeLookupResult usage
  bazelbuild/bazel#27994

Both 8.5.0 and 8.5.1 are fully backward compatible with Bazel 8.0.

## Dependency updates
- Upgrade rules_go from 0.57.0 to 0.59.0 for Bazel 8.5+ compatibility
  bazel-contrib/rules_go#4493
- Configure sh_configure extension for rules_shell to auto-detect shell toolchain

## Platform-specific changes
- Windows: Configure hermetic shell via --repo_env=BAZEL_SH which is used by both
  sh_configure (sh_binary/sh_test) and --shell_executable (genrule/run_shell).
  This eliminates dependency on system environment variables.
- Windows: Disable code coverage collection (--nocollect_code_coverage) to avoid
  shell toolchain issues. Coverage requires sh_binary (collect_coverage) which
  needs a hermetic shell toolchain not yet available.
