`eslint-plugin-react-hooks` was a `clients/web` devDependency only, and each
client's `eslint .` is scoped to its own directory — so the whole hook rule
set had never looked at `core/react/`, a directory of nothing but React
hooks. "Neither surface has JSX" was the stated reason and was never a good
one: the rules judge hooks, not JSX.
Add the plugin at the root and apply it in a `core/react/**` block (scoped
there rather than to all of `core/**`, since the rules key off the `use`
prefix), with `exhaustive-deps` promoted to `error` as `clients/web` does.
Resolve the 15 findings it then reports:
- `useSettingsDraft` / `useClientSettingsDraft` seed their draft during
render instead of in a `targetId`/`opened`-keyed effect, so the previous
target's values never reach the DOM — the same rule `clients/web` spells
`useValueChange`. Their "latest value" refs move from render-time writes
into an effect; every reader (the debounce timer, `flush`, `onChange`)
runs after a commit, so a post-commit write is what they need.
- The three async loaders keep their effects behind justified inline
disables: `set-state-in-effect` follows a call into an async function
without modelling the `await`, verified against a minimal hook whose only
setState is in a continuation.
- `useInitialConfig`'s cleanup bump keeps reading `generation.current` at
teardown — the rule's "copy it into a variable" advice would restore a
stale request token and let a superseded response commit.
