Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (6)

`calculate_bearing`	Calculate the initial true bearing between two GPS coordinates.
`calculate_cross_track_error`	Calculate cross track error (XTE) — the perpendicular distance from a vessel position to the great-circle track between two waypoints — plus side of track (port/starboard) and along-track distances.
`calculate_distance`	Calculate great-circle and rhumb-line routes between two GPS coordinates.
`convert_coordinates`	Parse latitude and longitude and format them as decimal degrees or DMS.
`convert_speed`	Convert a speed value between knots, mph, km/h, m/s, and ft/s.
`list_tools`	List the public Mariner GPS Tools calculators currently available.

Schemas: list_tools.
