chore: iterate the query cache maps through a single generator

[Nic-Polumeyv]

client.js walks query_map and live_query_map eight times across _invalidate and _goto, each as a hand-written for (const [id, entries] of map) for (const [payload, entry] of entries) pair, and five of those recompute create_remote_key(id, payload) inline to get the key the consumer actually wants.

This adds a cache_entries(map) generator yielding [key, entry] and collapses each site to a single loop. No behaviour change; the walk order and the set of resources touched are identical.

Please don't delete this checklist! Before submitting the PR, please make sure you do the following:

• It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs
• This message body should clearly illustrate what problems it solves.
• Ideally, include a test that fails without this PR but passes with it.

Tests

• Run the tests with pnpm test and lint the project with pnpm lint and pnpm check

Changesets

• If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running pnpm changeset and following the prompts. Changesets that add features should be minor and those that fix bugs should be patch. Please prefix changeset messages with feat:, fix:, or chore:.
