fix(ci): August model_experiment partitions and record.sh adb

[iscekic]

Summary

• Unblocks CI test after 2026-08-01: seed Aug–Oct model_experiment_request partitions and provision the rolling window in Jest (same pattern as Exa).
• Cron uses the shared provision helper.
• apps/mobile/e2e/record.sh finds adb via Homebrew android-commandlinetools (matches appium.sh / mobile-android.ts).

Test plan

• bash -n apps/mobile/e2e/record.sh
• pnpm exec tsx --test dev/local/appium-wrapper.test.ts (11/11)
• provision helper smoke for Aug 2026 window
• CI test green on this PR

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

High confidence: the extracted partition-provisioning helper is behavior-identical to the previous inline cron loop, the new 0201 seed migration matches the existing 0142 partition naming/bounds so it is a safe no-op where cron already provisioned Aug–Oct 2026, and the record.sh adb resolution mirrors appium.sh.

Verification notes

• 0201_snapshot.json is byte-identical to 0200_snapshot.json after removing id/prevId, and the journal chain (prevId linkage, idx: 201) is consistent — no schema drift.
• CREATE TABLE IF NOT EXISTS ... PARTITION OF is idempotent for the same partition name, and the parent's indexes propagate automatically to partitions attached later, so no per-partition index DDL is required here (unlike exa_usage_log, whose partial indexes are not defined on the parent).
• provisionModelExperimentRequestPartitions builds identifiers from format(target, 'yyyy_MM') only, so the sql.raw usage carries no injection surface; the unqualified table names preserve the pre-existing cron/migration behavior.
• Unit tests cover both the happy window and per-partition failure isolation; workerSetup.ts treats any provisioning failure as fatal, matching the Exa pattern.
