[frontend] scripts/export-abis.ts: Foundry out/ → packages/shared/abi.ts automation

[ozpool]

Context

Script that reads Foundry out/ and writes typed ABI constants into shared. Run after every forge build.

Ref: PRISM_PRD_v1.0.html §Day 1.

Scope

In scope:

• scripts/export-abis.ts
• Wired into Turborepo build task so it runs post-forge-build
• Outputs typed as const ABI objects

Out of scope:

• Manual ABI editing

Acceptance Criteria

• pnpm build regenerates shared ABIs
• All tx states rendered (idle/pending/success/error/wrong-network)
• wagmi v2 + viem v2 (not ethers)
• ABIs from packages/shared (never hand-maintained)
• Keyboard navigable; semantic HTML; WCAG AA contrast
• Responsive at 320 / 768 / 1280
• pnpm typecheck && pnpm lint && pnpm test pass

Dependencies

• Blocks: [frontend] Deposit form: paired amount inputs + approval flow + preview + tx state machine #52, [frontend] Withdraw form: share input + proportional preview + tx state machine #53
• Blocked by: [frontend] packages/shared: generated ABIs + per-chain addresses + shared TypeScript types #45
