feat: add weather, hazard, terrain and situation tools

Add get_weather, get_regional_brief, get_cyclones, get_fire_perimeters,
get_terrain_height, find_military_installations and get_map_features
over the application request services and the layers' sources.

situation_brief combines weather, earthquakes, fires, aircraft and
cyclones for an area by reusing those tools, marking sections that are
unavailable instead of failing. get_hud_caption returns the app's
heads-up display caption for the same overview.

 shared `area` argument (place name, bounding box, or point and radius) and cap
 lists at 25 rows by default. The app does not import the tools, so its runtime
 behavior is unchanged. See [tools and the MCP server](TOOLS.md).
