docs: document missing ESLint factory rules

[Copilot]

The ESLint factory README omitted two registered rules, leaving rule-reference documentation incomplete.

• Rule index

  • Add entries for prefer-structured-clone and require-fetch-response-body-try-catch.

• Rule references

  • Document detected forms, exclusions, and suggestion behavior from each rule’s implementation.

JSON.parse(JSON.stringify(value)) // prefer-structured-clone
await fetch(url).json()           // require-fetch-response-body-try-catch

Thanks for working on this documentation fix! 👋 This PR is aligned with the project's documentation improvement goals and the description clearly outlines the gaps and plan.

However, there's one thing to note before this can be reviewed for merge:

• Push the commits — This PR is currently in WIP/DRAFT state with 0 changes. The workflow run encountered a file-protection issue when trying to push signed commits (protected file: eslint-factory/README.md). Once the protected file protection is sorted out or the commits are pushed through an authorized mechanism, this PR will have actual changes ready for review.

Once commits appear, the review will focus on:

• Documentation parity between eslint-factory/README.md and eslint-factory/src/index.ts (the two missing rules)
• Content derivation from each rule's meta.docs.description and create() logic

Great work documenting the root cause and suggesting improvements to the Daily Documentation Healer workflow!

eslint-factory/README.md:284

• The implementation matches any identifier named fetch, without resolving whether it is the global binding. Calling these chains “global” is therefore inaccurate for locally shadowed fetch functions.

The rule recognizes direct global `fetch(...)` chains and identifiers assigned from a bare `await fetch(...)`. It supports direct or string-literal computed body methods, such as `response["json"]()`.

eslint-factory/README.md:293

• Deferred-callback calls are not out of scope: the rule deliberately ignores the outer try boundary and reports these calls because that handler cannot catch their later asynchronous failures. Listing them under “Out of scope” incorrectly implies they are not flagged.

- calls in deferred callbacks nested within a `try` block, because that `try` cannot catch their asynchronous failures
