fix(calm-suite): add workspaces field to calm-studio root package.json

multi-semantic-release runs from calm-suite/calm-studio/ as cwd. Without
a workspaces field in package.json it traverses up to the repo root, which
includes calm-ai and other packages outside the cwd, causing:

  Error: Path .../calm-ai/README.md is not in cwd .../calm-suite/calm-studio

Explicitly list the calm-studio sub-packages so multi-semantic-release
scopes its discovery correctly and the automated release workflow succeeds.
