feat: add gram install claude-code command for MCP server configuration

Implements a new CLI command that configures Gram toolsets as MCP servers in Claude Code. Supports both automatic toolset lookup via API and manual configuration with custom URLs and headers.

Also fixes missing ServeFunction endpoint in cli/internal/api/assets.go that was added to the generated code in PR #769 but not propagated to the handwritten client wrapper.
