claude[bot]andClaude f0e0865acc chore(studio): promote zero-baseline eslint ratchet rules to error (#50977)
<!-- ccr-slack-attribution -->

thread](https://supabase.slack.com/archives/C0161K73J1J/p1790599888647059?thread_ts=1790599888.647059&cid=C0161K73J1J)_

## Problem

The Studio ESLint "ratchet"
(`apps/studio/scripts/ratchet-eslint-rules.ts`, baseline in
`apps/studio/.github/eslint-rule-baselines.json`, tracked rules in
`apps/studio/scripts/ratchet-rules.json`) lets certain rules stay at
`warn` severity while CI blocks the *count* of violations from
increasing. Several of those tracked rules had already reached a
baseline of 0 allowed violations, meaning there's nothing left to
ratchet — they should be enforced directly instead of tracked
indirectly.

## Solution

**Before:** `no-restricted-imports`, `jsx-a11y/aria-props`,
`jsx-a11y/aria-proptypes`, `jsx-a11y/role-supports-aria-props`,
`jsx-a11y/anchor-has-content`, `jsx-a11y/aria-role`,
`jsx-a11y/no-aria-hidden-on-focusable`, `jsx-a11y/tabindex-no-positive`,
`jsx-a11y/no-distracting-elements`, and `react-hook-form/no-use-watch`
were all tracked in the ratchet baseline with a count of 0, and (apart
from `no-restricted-imports`, see below) configured as ESLint `warn` in
`apps/studio/eslint.config.cjs`.

**After:** each of those rules is removed from
`apps/studio/.github/eslint-rule-baselines.json` (both the `rules` count
and the now-empty `ruleFiles` entry) and from
`apps/studio/scripts/ratchet-rules.json`. Their severity in
`apps/studio/eslint.config.cjs` is bumped from `warn` to `error` so
they're enforced directly by lint going forward instead of being tracked
via the ratchet. `no-restricted-imports` was a special case: a later
config block in `apps/studio/eslint.config.cjs` already overrides the
shared `warn` default with `error` (confirmed via `eslint
--print-config`), so only the ratchet bookkeeping needed removing for
that rule — no severity change was needed.

Promoting `jsx-a11y/role-supports-aria-props` to `error` surfaced one
real violation that the ratchet's non-test-file filter had been hiding:
a mock `<button>` in `LocalDropdown.test.tsx` set `aria-checked`, which
that role doesn't support. Removed the unused `aria-checked` attribute
from the mock (it wasn't asserted on by any test).

Every other rule still tracked by the ratchet (e.g.
`@typescript-eslint/no-explicit-any`, `react-hooks/exhaustive-deps`,
`no-restricted-exports`, …) has a baseline above 0 and was left
untouched.

### How verified

- `pnpm --filter studio run lint:ratchet` → `Stable: No regressions for
selected rules.`
- `pnpm --filter studio run lint` → `0 errors, 2430 warnings` (no new
errors from the severity bumps)
- `npx vitest run components/interfaces/LocalDropdown.test.tsx` → 3/3
passing after the mock fix
- `npx prettier --check` on all touched files → clean
- `npx tsc --noEmit` shows one pre-existing, unrelated error in
`packages/ui-patterns` (reproduced identically on `master` before this
change)

## Review instructions

1. Confirm `apps/studio/.github/eslint-rule-baselines.json` and
`apps/studio/scripts/ratchet-rules.json` no longer list the 10 rules
named above.
2. Confirm those same rules (except `no-restricted-imports`, already
`error`) are now `'error'` in `apps/studio/eslint.config.cjs`.
3. Run `pnpm --filter studio run lint:ratchet` and `pnpm --filter studio
run lint` locally to confirm both pass.
