Version every published package and the shipped binaries at 1.0.0-alpha.0 via
Changesets pre-release mode. Add the MIT license, the install script and its
/install endpoint, and a tag-triggered release workflow.

Fixes found while releasing:
- .changeset/config.json ignored @initlabs/vibekit-mcp-reference, which no
  longer exists; the stale entry made every changeset command fail.
- verify-packed skipped prerelease tarball names, so the packed consumer
  resolved nothing.
- resolveExploreEntry never looked next to the running binary: in a compiled
  binary import.meta.dir is the virtual /$bunfs root, so an installed
  vibekit explore could not find its sidecar.

The CodeSandbox and StackBlitz templates were v4-era, had no Svelte entry,
and required manual upkeep on external accounts to stay current.

Point reporters at the in-repo examples/ directory instead. Those cover all
seven framework setups, are built in CI, and never go stale. CodeSandbox and
StackBlitz remain suggested as places to share a reproduction.
