v0.8.0-rc.1

This release includes a number of fixes and improvements for the experimental support for CUE modules first released in v0.8.0-alpha.1.

Modules

cue mod tidy gained a --check flag, which succeeds only if the module file contains exactly the required dependencies and also contains a canonical CUE language version.

cmd/cue and cue/load now send a detailed HTTP User-Agent string to CUE registries when sending HTTP requests, including the CUE and Go versions, rather than Go's default net/http user agent string.

cmd/cue now supports CUE_DEBUG=http to print HTTP logging information to stderr in JSON format.

Local builds of cmd/cue, such as running go install ./cmd/cue, now include a proper CUE version, allowing cue mod init and cue mod tidy to insert language.version as expected.
