Expose x_min/x_max/y_min/y_max, max_points, width/height, and title
override through the MCP tool. Data is clipped to X range before
stride-based downsampling for better zoomed resolution. All params
default to None/current behavior for backward compatibility.
Rename package from mcp-ltspice/mcp_ltspice to mcltspice throughout:
source directory, imports, pyproject.toml, tests, and README.
Remove startup banner prints from main() since FastMCP handles
its own banner and stdout is the MCP JSON-RPC transport.
