## Summary
- Follow-up to the axe-core accessibility audit (FE-3781), which found
1,733 failing elements across 126 Studio surfaces deduplicating to 12
root-cause families. A subset of those (missing accessible names/labels,
invalid/redundant ARIA, empty headings/anchors) is statically detectable
— this adds ESLint coverage for it instead of relying solely on the
runtime axe-core CI gate.
- Adds 13 `jsx-a11y` rules to `apps/studio/eslint.config.cjs` at
`'warn'`: `aria-props`, `aria-proptypes`, `role-supports-aria-props`,
`anchor-has-content`, `control-has-associated-label`
(`controlComponents: ['Button', 'Switch']`),
`label-has-associated-control` (`labelComponents: ['Label']`,
`controlComponents: ['Input', 'Switch']`), `aria-role`,
`no-redundant-roles`, `no-aria-hidden-on-focusable`,
`tabindex-no-positive`, `anchor-is-valid`, `heading-has-content`,
`no-distracting-elements`.
- Wires all 13 into the existing `lint:ratchet` script and initializes
their baselines in `apps/studio/.github/eslint-rule-baselines.json`, so
any *new* violation fails `studio-lint-ratchet.yml` while the
pre-existing ones (mostly `control-has-associated-label`: 274,
`label-has-associated-control`: 37) are tracked and shrink over time via
the weekly baseline-decrease cron.
Resolves
[FE-3795](https://linear.app/supabase/issue/FE-3795/add-jsx-a11y-eslint-ratchet-rules-for-statically-detectable-a11y).
## Test plan
- [x] `pnpm --filter studio run lint:ratchet` passes (exit 0, no
regressions)
- [x] Spot-checked several flagged instances against source to confirm
true positives (e.g. an unlabeled save/cancel icon-button pair in
`AIAssistantChatSelector.tsx`, an empty `<h3>` in `PITRForm.tsx`)
- [x] CI (`studio-lint-ratchet.yml`, typecheck.yml lint step) green on
this PR

## Summary by CodeRabbit
* **Bug Fixes**
* Expanded Studio’s accessibility linting to cover additional ARIA prop
validation, label/control relationships, anchor/heading validity,
role/ARIA correctness, and focus/tab behavior (including distracting
markup).
* Updated accessibility lint baselines so tracked violations remain
accurate as rules expand.
* **New Features**
* Enhanced the Studio lint “ratchet” workflow to load ratchet rule IDs
from an external `rules-file` instead of a long inline command.
* **Tests**
* Added an integration test to verify rule IDs are read from the
`rules-file`.

**Stack 1/6** of the TanStack Start migration (#46424), split into
reviewable, independently-mergeable PRs.
> [!IMPORTANT]
> **Next stays the default and only active framework after this PR.**
This wires up the Vite/TanStack-Start build pipeline behind the
`STUDIO_FRAMEWORK` flag, but there are no TanStack routes yet — so the
TanStack build isn't functional or tested until later PRs in the stack.
Nothing about the Next build, dev, or deploy changes behaviourally here.
## What's in this PR
- **Dispatch:** `dev`/`build`/`start` now go through
`scripts/dispatch.js`, which runs the Next variant unless
`STUDIO_FRAMEWORK=tanstack`. The original commands are preserved as
`dev:next`/`build:next`/`start:next`.
- **Build pipeline:** `vite.config.ts`, `serve.js`, `smoke-server.mjs`,
vite/tanstack deps, `turbo.jsonc`.
- **`tsconfig.json`:** `jsx: react-jsx`, `moduleResolution: Bundler`,
`target: ES2022`. Because `include` is `**/*.ts(x)`, this re-typechecks
the whole app, so the companion adaptations below land with it.
- **Shared adaptations (companions to the tsconfig change):**
`BufferSource` casts, `packages/ui` unused-`React` import removals, etc.
- **Routing/middleware plumbing:** `next.config.ts` +
`redirects.shared.ts` (redirect rules now shared with `vercel.ts`),
`proxy.ts`/`start.ts` middleware + `hosted-api-allowlist.ts`.
## Verification
Run locally off `master`: frozen install ✓, `studio` typecheck ✓, **Next
build ✓** (compiles + generates all routes), lint ratchet ✓ ("some rules
improved"), prettier ✓.

## Summary by CodeRabbit
* **New Features**
* Added a hosted API endpoint allowlist to return 404 for non-supported
`/api/*` routes.
* Introduced a TanStack route-migration checklist and expanded TanStack
Start routing support.
* **Improvements**
* Enhanced deployment refresh/detection by tightening cookie handling
for “latest deployment” updates.
* Centralized redirect/maintenance-mode rules for consistent platform vs
self-hosted behavior.
* Improved production serving with a dedicated static + proxy server and
a post-build smoke test.
* **Dependencies**
* Updated TanStack-related packages and React Table/query tooling
versions.
* **Documentation / Chores**
* Updated formatting and tooling config; added shared build environment
parsing utilities.

Proposed mitigation, the obvious tradeoff is that clearing the cache
will make compilation slower on subsequent dev server starts, but more
consistent.
Various people have been observing `next-server` use up to ~34 GB
memory. I've observed 12.59 GB memory, with ~1.5k `postcss` processes:
```
ps aux | grep postcss | grep -v grep | wc -l
1526
```
Going down to 3 `postcss` process and 4.71 GB memory after clearing
cache:
```
ps aux | grep postcss | grep -v grep | wc -l
3
```

## Summary by CodeRabbit
* **Chores**
* Development infrastructure: adds an automated pre-development step
that clears the local dev cache before starting the development server
by introducing a new lifecycle hook and supporting cleanup script;
purely maintenance-oriented with no user-facing changes or functional
impact.

* chore: add eslint ratchet script
* chore: add eslint ratchet action
* refactor(ratchet script): convert to typescript
* ci(ratchet script): add --decrease-baselines flag
Allows us to decrease the baselines on schedule as we fix warnings
* ci(ratchet): add action to decrease baseline if possible every week
* chore(eslint): fix exhaustive-deps error
* docs(internal): improve docs for eslint ratchet script
* chore(ratchet): add new ratchet rules
Add:
- import/no-anonymous-default-export
- @tanstack/query/exhaustive-deps
- @tanstack/query/no-deprecated-options
Not adding `no-restricted-exports` even though we have many violations
because we first need to reconfigure it (if possible) to ignore those
files where Next.js requires a default export.
* Update Supabase docs URLs to use env variable
