croquis 0.1-0

Initial public beta release.

Introduced the Simplified Speed and Frequency Specification (SSFS), a data structure for simplified transit network creation and editing. SSFS objects contain 8 component tables (agency, routes, stops, itin, stop_seq, span, hsh, calendar) and can be constructed with ssfs(), validated with validate_ssfs(), and printed with a compact print.ssfs() summary.
Added ssfs_to_gtfs() for converting SSFS objects to valid GTFS feeds, with optional shape_dist_traveled output. Output is compatible with downstream analysis tools such as r5r and gtfstools.
Added gtfs_to_ssfs() for converting existing GTFS feeds into SSFS format for editing. Supports route filtering, date windowing, parallel processing on Unix-like systems, and both OSRM and Valhalla routing servers for shape generation.
Added ssfs_subset() for filtering SSFS objects by route or itinerary, with retain or remove operations.

Launched the Croquis interactive Shiny application via croquis(). The app provides a complete workflow for transit sketch planning: create or import a transit network, manage stops, draw routes along streets or in free mode, define schedules with headway-based service patterns, and export to GTFS or save as a Croquis project file (.rds).
Modules include: Home (project setup, agency management, GTFS/project import), Stops (create, edit, import/export, auto-generate from OSM), Routes (route and itinerary management, stop sequences, network or free drawing mode), Schedule (service calendars, service windows, headways and speeds by hour, speed recalculation), and Export/Save.
Internationalization (i18n) support for English, French, and Spanish across the full interface, with live language switching.

Added apply_gtfs_speeds_to_ssfs() for calibrating SSFS speeds using a reference GTFS. Builds a temporal-spatial interstop speed matrix and applies observed speeds by hour and segment to a target SSFS. Falls back to routing-based speed estimates for segments not covered by the reference GTFS.
Added gtfs_to_interstop_matrix() and apply_interstop_matrix_to_ssfs() as lower-level alternatives to apply_gtfs_speeds_to_ssfs().

Added generate_tdrh() for computing trips, distance, and runtime by hour for specified routes or itineraries and services.
Added generate_service_cost() for computing total daily service hours and service kilometers by agency.

Added gtfs_remove_routes() and gtfs_retain_routes() for filtering GTFS objects by route.
Added ssfs_subset() for filtering SSFS objects by route.

Included 7 sample datasets: ligne_jaune (STM Yellow Line), stm_metro (full STM metro), mileend (STM Mile-End bus subset), ttc_subway (TTC subway), translink (Translink Vancouver), gtfs_rct (Railway City Transit GTFS), and ssfs_rct2 (Railway City Transit redesign scenario).

Added a “Produce a GTFS” vignette with a full walkthrough using the Toronto Island Ferries as a worked example.
Added a “SSFS data structure” vignette that provides an overview of the data structure introduced by this package designed to facilitate rapid network and schedule production and conversion to GTFS.
