Implements the Terraform Registry Protocol as a proxy remote type so
Terraform and OpenTofu can pull providers through the caching layer
without changing provider source addresses.
- New `terraform` package type with `construct_url` (prepends
`/v1/providers/`) and `resolve_content` (rewrites `download_url`,
`shasums_url`, `shasums_signature_url` to route through a companion
`releases_remote`)
- Built-in mutable pattern for provider version lists
(`{ns}/{type}/versions`)
- `releases_remote` config option links the registry remote to a
separate generic remote proxying the release CDN
- Client config: `.terraformrc` / `.tofurc` host block redirects
`registry.terraform.io` to the proxy without touching `.tf` files
- 8 unit tests + end-to-end test (OpenTofu 1.10 pulling hashicorp/vault
4.5.0 through docker-compose stack)
- Example config and README section added
