Depends on #179, #181, #185, #186, #187 and #188. Base frlg/rng-plan-base: frlg/autostory-starter-rng (#179) with #181, #185 (frlg/trainer-card) and #188 (frlg/rng-plan-log, which carries #187 and #186) merged in, so the diff shows only the AutoStory glue.

The Starter RNG stop told the user to run Starter RNG but not with which seed, and with the SID only narrowed to SID Helper's candidates there was no plan for finding a shiny. Now the stop reads the TID off the Trainer Card and lists the attempts to make, in order.

• The pieces that don't need AutoStory are split out: target search (FRLG: search static/gift/starter RNG targets in the program #181), the shared Trainer Card navigation and try_read_tid() (FRLG: share the Trainer Card navigation and TID read #185), option parsing (FRLG: parse RNG plan inputs (TID, IVs, natures) #186), the plan and tracker (FRLG: plan RNG attempts over SID candidates and track their outcomes #187), and the log lines (FRLG: RNG plan log lines and RngPlan tests #188). This PR only wires them into AutoStory.
• New "RNG Plan" option group (PokemonFRLG_AutoStoryRngOptions): sound, TID (empty: read from the card), SID (empty: SID Helper's candidates), SID Helper's Target Advances and # candidates, shiny required, natures, minimum IVs, max attempts. Their text is checked before anything is pressed.
• Under the ball, just before 00.04 saves, AutoStory opens the Trainer Card, reads the TID (skipped when the TID option is filled in), closes it and builds the plan. A TID it can't read, or no target, ends the run before that save, so 00.03's save still starts 00.04 once the option is fixed; it never plans with a made-up TID. The stop message, log and overlay list each attempt's Target Seed, Advances, nature, IVs and the SIDs it's shiny for, with both Starter RNG waits.
• Manual for now: the user runs Starter RNG per attempt. Calling it in-process is FRLG: make Starter RNG's attempts and SID Helper's steps callable #183/FRLG AutoStory: run Starter RNG in the program (option, off by default) #184.
• New "RNG Calibration (this console)" group inside the RNG plan keeps the console's seed (ms) and Continue Screen Frames offsets, in Starter RNG's units, for the in-program RNG stops (FRLG AutoStory: run Starter RNG in the program (option, off by default) #184, FRLG AutoStory: run Gift RNG for the Magikarp after 00.12 #192) to start from and save back to.
• TODO: LeafGreen and Bulbasaur/Charmander; this is FireRed with Squirtle only, like the rest of AutoStory.

Testing: the plan's suites (PokemonFRLG::RngPlan, RngPlanTracker, RngPlanInputs, RngPlanLog, RngTargetSearch) now live in the split PRs and passed before the split in a harness linked against the lab build. This PR's files were syntax-checked only, not built; CI is dispatched. Nothing ran on a console, so the card read at the stop is unverified.
