Depends on #148 (base bdsp/actions-v4); the diff shows only this PR's change.

BDSP AutoStory rewritten like FRLG's: one table of story steps from 00.00 to 01.11, run by #122's shared engine with its checkpoint dropdowns and stats, written in the shared story steps (ROUTE, LEGS, STEP, TALK, MASH, BATTLE, HEAL) instead of segment functions replaying recorded stick holds.

• Walks are routes planned on the JSON maps onto the decomp's scene triggers and coord events, with Developer-Butters' button sequences from [WIP] BDSP Autostory PokemonAutomation/Arduino-Source#1717 for the scenes (credited). 01.05–01.10 (folded in from BDSP AutoStory: plan 01.05 to 01.10 on the story maps #175) are map-planned routes and door taps that wait for the location banner; 01.08 starts from the wall west of Rowan's scene.
• Most named events are now shared steps (folded in from BDSP AutoStory: the story table's named events as shared story steps #173); Events_*.cpp is 725 lines (1,487 before). Still named, because the shared steps don't cover them: the Azure Flute, briefcase, starter choice, catching tutorial and catch (BDSP-only menus and scripts), 00.04c's Mart lady (checks two signs, looks for her up to three times), 00.04d's stairs (Dawn's scene is not on Diamond's trigger), 00.05b's wandering clowns, 01.04's gym loop (walks back from the Center after a loss to keep the experience), and 01.09's Rock Smash (Yes/No box).
• Maps: the mine's entrance hall (from the decomp), the coal room as a room world, and the mine's warp tiles as doors. TALK waits 8 s for a line (Roark's comes after a camera zoom, r98).
• Start-save check: a row that saves first names its start map (saves_in). The start save reads the save screen's place name and, if it is not that map, backs out unsaved and stops with FatalProgramException, so a run never saves over a good checkpoint from the wrong place (r76/r77 did).
• A Pokemon Center is its warm floor (at least 30% of the screen) in a room (indoors()); Jubilife's yellow plaza read as a Center and a won battle was called lost (r79).
• Fixes from console runs r9–r103 (each named in its commit): door steps watch for the fade themselves, talks turn to the pose's facing first, Center doors in and out, the Ravaged Path exit, settling while Floaroma's cloud shadows move.
• Small changes to parent PRs' files that the table needs: town plan costs for D-pad legs, Route 201's measured path in RouteRecords and Segment00Lines, and the Center test in the Walk suite.

Testing

• Suites: StoryTable (lints: a row has saves_in exactly when it saves first, each row starts where the last ends, town routes take the short way), StorySimulation (the whole story in English and Japanese, every route planned), and Walk. Offline on BDSP AutoStory: grid simulation of walks and scenes for unit tests #167's grid simulation (throwaway merges, not part of this PR), every row from 00.04d to 01.11 ends on its table tiles.
• Console: the start-save check stopped as meant on console B (01.10 started in Floaroma read "floaromatown" and stopped unsaved).
• Not run on the console yet (from BDSP AutoStory: the story table's named events as shared story steps #173's and BDSP AutoStory: plan 01.05 to 01.10 on the story maps #175's checks): 00.02's Lakefront scene end at (17, 14/15); 00.03's Pokedex scene ending at Rowan; 00.05's start at (48, 62) and Barry's Town Map talk; 01.01's step onto Barry's coord event; 01.02's Gate trainers and Oreburgh welcome scene; 01.03's Center door column (47, not 46), the mine's warps and 19-tap hall, Roark's talk and scene timing; 01.04's 20 taps from where the heal leaves us; 01.05–01.10's routes and door banners; 01.11's 8 taps west and the old couple's talks.
