Depends on #182 (base frlg/autostory-rng-plan; the diff shows only this change).

AutoStory needs to run Starter RNG's attempt loop and SID Helper's naming-screen steps, but both lived inside their programs with the programs' own options. This prep refactor, with no behaviour change, moves the loop into StarterRngAttempts (target, settings, displays, notifications and stats come from the caller; run() returns shiny / target hit with the target's PID, nature and IVs / wild shiny / out of resets / no matches) and moves set_sid_from_name_screen, finish_intro_animations and the delay computation (sid_timing) into PokemonFRLG_SidSteps. StarterRng and SidHelper now call these with the same presses, waits, logs, stats and notifications; StarterRng still fires the "no matches" error itself. Two additions for AutoStory are off for StarterRng, so it runs as before: an on_reset hook called after each reset, and identify_shiny, which reads a shiny starter's summary and searches near the target. With it on, a shiny comes back as shiny_on_target or shiny_off_target.

The bodies are moved unchanged except where long functions were split to pass code health (about 40% of changed lines show as moved): git diff --color-moved=dimmed-zebra --color-moved-ws=allow-indentation-change frlg/autostory-rng-plan...frlg/rng-callable-steps.

Tested by compiling the touched files locally with -Wmissing-designated-field-initializers and code health (0 failures); new PokemonFRLG::RngSteps unit tests cover the SID timing per language, the per-starter tables and identify_shiny(). All pass in a test runner linked against a local full build. Not run on a Switch.

• on_read (off for StarterRng): after each reset's reads, the attempts hand the caller the search hits and the state the calibration took as hit (reset_hit(), tested in PokemonFRLG::RngSteps), for AutoStory's one line per reset.
