edr4r (development version)

• Quote software and API names in DESCRIPTION, and document the output class and meaning for every exported function help topic.
• Parse RFC 3339 datetime offsets correctly and preserve datetime axes as character when any value cannot be parsed.
• Validate client settings, bounding boxes, datetime/limit filters, and radius/corridor dimensions before sending requests.
• Preserve leading zeros in CSV identifier and code columns.
• Reject CoverageJSON ranges whose shapes, axes, and values disagree.
• Warn when station maps use unlimited inexact nearest-coordinate matching, and retain multiple coverage coordinate groups matched to one station.
• Add edr_parameter_groups() for optional cross-collection parameter mappings advertised by some deployments.
• Skip location discovery for explicit cube, area, and position edr_explore(output = "data") queries when the locations response would not be consumed.
• Make edr_explore(method = "auto") try advertised area queries before location discovery, then honor polygon coords when falling back from a missing or unavailable area endpoint by bounding and spatially filtering locations before per-location requests.
• Preserve mixed numeric/text CoverageJSON values as character instead of silently converting text values to NA.
• Make edr_explore(method = "auto") choose bulk spatial queries only when the matching spatial input is supplied.
• Add grid and vertical-profile plot views to edr_plot(), with automatic view detection.
• Allow edr_explore() to return plots or data for gridded/profile coverage queries, including method = "position" for profile-style responses.
• Add interactive coverage maps to edr_map() and edr_explore(), with in-map selectors for gridded coverage slices (parameter, datetime, z) and profile selectors for parameter / datetime.
• Materialize CoverageJSON regular-grid axes declared with start, stop, and num, as used by the WWDH usgs-prism collection.
• Warn when per-station edr_explore() fallback fetches fail.
• Tighten collection-id, coordinate, and WKT validation.
• Add max_match_distance to edr_map() for bounded spatial matching.
