Depends on #191 and #189 (base frlg/autostory-route3, with frlg/gift-rng-callable-steps merged in, so the diff also shows #189's GiftRng* files; this change alone is commits 6701329, 72430b5, 5c37581 and ed05b85).

AutoStory can now buy the Magikarp from Route 4's salesman with Gift RNG in the program, the way it already runs Starter RNG, and save a shiny one.

• New GIFT_RNG handoff on 00.12 (saved facing the salesman) and a Run Gift RNG in AutoStory option, off by default, so runs without it are unchanged.
• The attempts are planned from the RNG plan's TID and SID just before 00.12 saves, so a planning failure keeps 00.11's save. Magikarp's English timings equal Starter RNG's (title, Continue Screen, 7,500 ms in game), so the plan reuses plan_starter_rng(); other languages are refused.
• ConsoleGiftRngSteps runs GiftRngAttempts as the RNG plan loop's steps, mapping its outcomes onto the loop's.
• New live-start row 00.12b leaves the summary (or HOME, after the Gift RNG program) and saves the shiny where 00.12 ended; the way back in after a by-hand Gift RNG run too.
• Starting at 00.12b with the option on loads the save beside the salesman (checked as Route 4), runs the attempts there and goes on with 00.12b for a shiny, so a failed attempt or a hand-made save at 00.12's end can be retried without replaying 00.12. With the option off, 00.12b runs as before.
• program() now runs its plan as a loop of handoffs, so a run with both Starter RNG and Gift RNG on goes from one to the other.
• Gift RNG starts from the console's seed and CSF calibration and its own in-game offset (GIFT_INGAME, 0 until saved, not Starter RNG's), and saves each reset's calibration back, as Starter RNG does.

Testing

• Syntax-checked every changed file with the build's flags (-Wall -Wextra -Werror); code health 0 failures against frlg/autostory-route3.

• New and updated unit tests in the AutoStory and AutoStoryRngLoop suites: run plans with the Gift RNG handoff, rows after a shiny Squirtle (now on to Gift RNG's stop) and after a shiny Magikarp, the 00.12/00.12b rows, Gift RNG's messages and its outcomes in the RNG plan, and run plans started at 00.12b with and without Gift RNG. Not run locally; CI dispatched.

• Not run on a console yet.

• Gift RNG's resets get the same one-line overlay entry as Starter RNG's (Gift RNG try 28/50: seed 9cf3 = target, advance 1669 (target 1670, -1). Missed.); Gift RNG's attempts report their reads through on_read.
