builtbykev 1265c23305 Tier-A joins: handedness, true role, and the velo fix
Three Layer-2 prerequisites, each one free call.

HANDEDNESS — statsapi /sports/1/players carries batSide, pitchHand AND
primaryPosition for every player: 1,316/1,316 in the live probe. Batter
handedness was 100% absent, which made every platoon or switch-flavour
archetype unbuildable; it is now populated from the same call that gives
pitchers theirs, with statsapi as the authority and the movement feed as the
fallback.

ROLE — statsapi season pitching with playerPool=ALL returns 751 rows (the
default returns only the ~57 qualified). Real usage: gamesStarted, gamesPitched,
gamesFinished, saves, holds. roleDetail derives starter/closer/setup/reliever
from that instead of the season-IP proxy, which drifts all year as innings
accumulate and left 32 pitchers in a 60-80 IP trough.

VELO — recovered from 53% to 99% (721/729 pitchers). The movement feed carries
only each pitcher's PRIMARY pitch, so matching by position could never do
better than one pitch each. The wide pitch-arsenals feed has one column per
pitch type, matched BY TYPE: Skubal now has velo on all 5 of his pitches. Velo
archetypes are therefore buildable rather than shelved.

Migration 032 applied.
