Migrate from ESLint to OxLint (#18443)
## Summary

Fully replaces ESLint with OxLint across the entire monorepo:

- **Replaced all ESLint configs** (`eslint.config.mjs`) with OxLint
configs (`.oxlintrc.json`) for every package: `twenty-front`,
`twenty-server`, `twenty-emails`, `twenty-ui`, `twenty-shared`,
`twenty-sdk`, `twenty-zapier`, `twenty-docs`, `twenty-website`,
`twenty-apps/*`, `create-twenty-app`
- **Migrated custom lint rules** from ESLint plugin format to OxLint JS
plugin system (`@oxlint/plugins`), including
`styled-components-prefixed-with-styled`, `no-hardcoded-colors`,
`sort-css-properties-alphabetically`,
`graphql-resolvers-should-be-guarded`,
`rest-api-methods-should-be-guarded`, `max-consts-per-file`, and
Jotai-related rules
- **Migrated custom rule tests** from ESLint `RuleTester` + Jest to
`oxlint/plugins-dev` `RuleTester` + Vitest
- **Removed all ESLint dependencies** from `package.json` files and
regenerated lockfiles
- **Updated Nx targets** (`lint`, `lint:diff-with-main`, `fmt`) in
`nx.json` and per-project `project.json` to use `oxlint` commands with
proper `dependsOn` for plugin builds
- **Updated CI workflows** (`.github/workflows/ci-*.yaml`) — no more
ESLint executor
- **Updated IDE setup**: replaced `dbaeumer.vscode-eslint` with
`oxc.oxc-vscode` extension, configured `source.fixAll.oxc` and
format-on-save with Prettier
- **Replaced all `eslint-disable` comments** with `oxlint-disable`
equivalents across the codebase
- **Updated docs** (`twenty-docs`) to reference OxLint instead of ESLint
- **Renamed** `twenty-eslint-rules` package to `twenty-oxlint-rules`

### Temporarily disabled rules (tracked in `OXLINT_MIGRATION_TODO.md`)

| Rule | Package | Violations | Auto-fixable |
|------|---------|-----------|-------------|
| `twenty/sort-css-properties-alphabetically` | twenty-front | 578 | Yes
|
| `typescript/consistent-type-imports` | twenty-server | 3814 | Yes |
| `twenty/max-consts-per-file` | twenty-server | 94 | No |

### Dropped plugins (no OxLint equivalent)

`eslint-plugin-project-structure`, `lingui/*`, `@stylistic/*`,
`import/order`, `prefer-arrow/prefer-arrow-functions`,
`eslint-plugin-mdx`, `@next/eslint-plugin-next`,
`eslint-plugin-storybook`, `eslint-plugin-react-refresh`. Partial
coverage for `jsx-a11y` and `unused-imports`.

### Additional fixes (pre-existing issues exposed by merge)

- Fixed `EmailThreadPreview.tsx` broken import from main rename
(`useOpenEmailThreadInSidePanel`)
- Restored truthiness guard in `getActivityTargetObjectRecords.ts`
- Fixed `AgentTurnResolver` return types to match entity (virtual
`fileMediaType`/`fileUrl` are resolved via `@ResolveField()`)

## Test plan

- [x] `npx nx lint twenty-front` passes
- [x] `npx nx lint twenty-server` passes
- [x] `npx nx lint twenty-docs` passes
- [x] Custom oxlint rules validated with Vitest: `npx nx test
twenty-oxlint-rules`
- [x] `npx nx typecheck twenty-front` passes
- [x] `npx nx typecheck twenty-server` passes
- [x] CI workflows trigger correctly with `dependsOn:
["twenty-oxlint-rules:build"]`
- [x] IDE linting works with `oxc.oxc-vscode` extension

Why Twenty

We built Twenty for three reasons:

CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.

A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.

We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
