v0.3.0

• Fix: Lay Track drag now starts and ends on a station when pressed on its building (snap to the station's tile), so dragging from one station to another works as in the original
• Feature: city names and free map labels (seas) are written above the map, station names when zoomed in; vector text, hidden when too far out, overlap-free
• Feature: the editor's tool panel uses the original bp*.imb art (height, paint, fill, trees, territories, add, bulldoze, overview) with the message strip bpmisc, scaled to the window, with click areas over the art (Kind::Hotspot in rt2-ui)
• Feature: Map Options pages Players (add/delete, persona, mandatory/optional, human/computer/either, cash), Player Pool, Managers, Engines, Ports and Robbers, with the player summary of the header kept as the original's editor does
• Feature: New Map > From Image (PCX heights with height scale 1..2000) and Remove Territory in Territory Setup
• RE: Map Options byte maps (players pool 0x574c68 +0x530..0x533, header summary 0x567c88/0x567ca0, player pool 0x567d40, managers 0x570638, engines 0x570667, port rows 0x57023b, robbers 0x573da2, robbery level 0x5704a8) and the PCX import (0x469bc0, 0x469670) documented in docs/formats/map-gam.md section 10
• Feature: scenario effect 233 floods a territory like the original (0x4c8a30 and the mode 3 water fill of 0x490490: trains, stations, track, buildings, rivers and roads cleared, water painted, corners set to the level).
• Feature: scenario effects 299/302 demolish stations and effect 189 removes the company's stations and track (building_destroy 0x40adb0 -> station_remove 0x4bf4e0, 0x437ab0 with destroy).
• Fix: demolishing a farm repaints the fields with the overlay lists as loaded (FieldDemolition identical to the original).
• Fix: a demolished building's cargo pile clears the lots' industry and frees those not in a car (0x40adb0).
• RE: the AI stop ratio 0x57951c is a run-time global that outlives a turn; ai_replan_train out of the AI turn (station removal) reads it.
• Docs: fidelity scoreboard 131/131 identical with the new prepared cases Flood, ConfStations and Deactivate (rt2-savepatch --add-rule, prepare_rare.py recipes, ADV_ADVHOOKPY in advance_gdb.py).
