fix: migrate workspace/project IDs to string and widen schema enums

- Change workspace id/projectId from z.number() to z.union([z.string(), z.number()]).transform(String) for backward compat
- Add "non_git" to projectKind, "local_checkout" to workspaceKind enums
- Session converts numeric IDs to strings at the descriptor boundary
- Update tests and daemon-client event types to match
