New visualize_tides and visualize_conditions MCP tools that generate
PNG (inline via MCP ImageContent) or interactive HTML (Plotly) charts.
Optional dependency group [viz] keeps the base install lightweight.
- charts/ package: rendering logic separated from MCP tool wiring
- Shared marine color palette (ocean blue, teal, slate, sand, coral)
- 14 new tests (parsing, PNG/HTML rendering, tool registration)
- Example chart images in README with realistic synthetic tidal data
