Add environment-specific claude-code package distribution system

Development environments now use standard nixpkgs claude-code by default.
Work environments override with custom binary distribution to bypass
corporate npm registry restrictions via Google Cloud Storage.

+  # Claude Code Package Override for Corporate Work Environment
+  #
+  # This overlay overrides the default claude-code package specifically for work environments
+  # where corporate network restrictions may prevent access to npm registry distributions.
+  #
+  # Context:
+  # - The default claude-code package (used in home environments) fetches from npm registry
+  # - Corporate firewalls and security policies often block npm registry access
+  # - Our custom claude-code package uses Google Cloud Storage distribution as a workaround
+  # - This maintains the same package name across environments while adapting to network constraints
+  #
+  # Environment-specific behavior:
+  # - Home environments: Use standard npm-distributed claude-code package
+  # - Work environments: Use custom binary-distributed claude-code package from GCS
+  #
+  # This approach ensures consistent tooling availability regardless of network environment
+  # while respecting corporate security policies.
