The slices package provides type-safe generic replacements for the
old typed sort convenience functions. The codebase already uses
slices.Sort in 43 call sites; this finishes the migration for the
remaining 29.
- sort.Strings(x) -> slices.Sort(x)
- sort.Float64s(x) -> slices.Sort(x)
- sort.StringsAreSorted(x) -> slices.IsSorted(x)
Fixes flaky `TestWorkspaceTagsTerraform` and
`TestWorkspaceTemplateParamsChange` tests that were failing with
`connection reset by peer` errors when downloading the coder/coder
provider.
This applies the same caching solution which was done in
https://github.com/coder/coder/pull/17373
1. Extracts provider caching logic into `testutil/terraform_cache.go`
2. Updates TestProvision to use the shared caching helpers
3. Updates enterprise workspace tests to use the shared caching helpers
The cache is persisted at `~/.cache/coderv2-test/` and automatically
cached between CI runs via existing GitHub Actions cache setup.
