8.0.0-rc1

First release candidate for v8.0.0 of all packages.

• Full rewrite to TypeScript
• New deploymentStrategy: "removeBeforeDeploy" option in exoframe.json - removes old deployment only after new image is successfully built
• JSON Schema for exoframe.json with editor autocomplete support
• exoframe logs now supports --tail and --since filtering options
• Fix server tearing down existing deployment when build fails
• Fix missing exoframe.json returning raw 502 instead of descriptive error
• Fix broken secrets route
• Fix server version check fetching from wrong GitHub repo
• Fix streaming response logging in client

In theory should be stable, but will be tested before final release.
Use with caution.
