docs: drop a redundant eslint directive and note a Bun test quirk

no-explicit-any is off repo-wide in eslint.config.js, so the disable comment
the plan mandated is itself an unused-directive warning. The test's schema
binding also needs the _ prefix the lint config requires for a value read
only via typeof.

Separately: bun test strips type-only imports before resolution, so the
red-first step does not reproduce for type-only tests. Recorded so later
implementers do not chase it.

 - Only procedures explicitly marked `.idempotent()` may be retried.
 - Errors crossing an app boundary are opaque by default: code and message only, no stack, no internal detail.
 - Test files live in `packages/<pkg>/test/*.test.ts` and use `import { describe, expect, test } from "bun:test"`.
+- `bun test` strips type-only imports before resolution, so a "verify it fails" step does NOT reproduce for a test whose only import from the new module is `import type`. Expect it to pass; that is a Bun behaviour, not a missing failure.
 - Test fixtures must NOT be scaffolded under `os.tmpdir()`. A scaffolded file importing `@wrnexus/*` by bare specifier cannot resolve outside the repo tree. Use a repo-local `.tmp-*` directory (`**/test/.tmp-*/` is gitignored).
 - Do NOT use `git stash`. This repo has `core.autocrlf=true`; a stash round-trip rewrites files to CRLF and fails `format:check`.
 - Write control-character checks as codepoint loops, never regex literals — escapes get mangled on the round-trip through tooling in this repo.
