📝 docs(test): follow-up scope for finishing the Anvil-to-Tevm migration

[roninjin10]

Review-only PR. Adds test/FOLLOWUP-tevm-migration.md: a single markdown file, no code, no CI, no site changes.

Why

I reviewed PR #2 (Complete the Anvil-to-Tevm test migration, 291 files) and posted findings as comments there:

• Complete the Anvil-to-Tevm test migration #2 (comment) — migration correctness
• Complete the Anvil-to-Tevm test migration #2 (comment) — dropped coverage + triage of the reported failures
• Complete the Anvil-to-Tevm test migration #2 (comment) — follow-up scope (this file)

Headline: several of PR #2's "known issues" look like migration bugs rather than Tevm gaps, and conflating them risks writing off real defects.

Verified locally

On PR #2's branch (f8618fe), after pnpm install --ignore-scripts (exit 0, tevm 1.0.0-rc.151):

$ pnpm exec vitest run -c test/vitest.config.ts --project core \
    src/actions/wallet/requestAddresses.test.ts src/utils/signature/verifyTypedData.test.ts
 Test Files  2 failed (2)
      Tests  3 skipped (3)
     Errors  4 errors

$ VITE_TEVM_NO_FORK=true pnpm exec vitest run -c test/vitest.config.ts --project core \
    src/actions/wallet/requestAddresses.test.ts src/utils/signature/verifyTypedData.test.ts
 Test Files  2 passed (2)
      Tests  2 passed | 1 skipped (3)

Two files that need no fork state cannot run without an archive RPC, because isUsed() in test/src/tevm.ts is tripped by any property read rather than by actual node use.

Scope of this PR

Documentation only. site/ is untouched (vocs sources live under site/pages; this file is under test/), so the live docs build is unaffected. Nothing merged.
