I am the codeowner of memory allocation tracking infra. However, this has meant that I get added as a reviewer on every PR which alters the snapshot files (notably a torrent of PRs on minifier, which I know nothing about). This makes it harder to track what PRs I _should_ actually be looking at.
Attribute ownership of the snapshot files to the codeowners of the relevant crates. This seems more logical.
I'm not actually the primary owner of this code - @ShanonJackson is. But add me to codeowners file, so I get added as a reviewer on any PRs touching the crate, so I don't miss them.
## What
Ports the Relay `graphql` tagged template transform (babel-plugin-relay / swc_relay) as an individual napi transform, per #24914:
- **`crates/oxc_relay`** — the core transform as its own crate (modeled on `oxc_react_compiler`): replaces `graphql` tagged templates with references to relay-compiler artifacts. Definition names are extracted textually like `swc_relay` (equivalent to `\b(fragment|mutation|query|subscription)\s+(\w+)` with `#` comments stripped; hand-rolled scanner, no regex dependency).
- **`napi/transform-relay`** (`oxc-transform-relay`) — standalone napi package copied from the `napi/transform-react` template: parse → semantic → relay traverse → codegen. Only `graphql` tags are rewritten; TypeScript/JSX syntax is preserved untouched, so the output composes with any downstream toolchain.
## Options
| option | default | behavior |
|---|---|---|
| `artifactDirectory` | unset | when set, the import path is computed lexically relative to the transformed file (babel-plugin-relay `getRelativeImportPath` semantics — swc emits absolute paths instead); unset → `./__generated__/` next to the file |
| `language` | `javascript` | `typescript` imports `Name.graphql.ts`, otherwise `Name.graphql.js` |
| `eagerEsModules` | `true` | hoisted default imports (babel-plugin-relay ≥ v17 parity); `false` emits inline `require()` (`@swc/plugin-relay` / Next.js behavior) |
A `graphql` tag with no extractable definition name produces an error diagnostic (babel throws; swc silently skips).
Not supported, documented in both READMEs: dev-mode artifact hash validation, `jsModuleFormat: "haste"`, `isDevVariableName`, swc's Next.js-specific `projects`/`pagesDir`, and GraphQL document validation.

---
Implemented with Claude Code.
This excludes the generated oxlint config from @overlookmotel ownership because it is updated by linter config changes and creates very noisy review requests.
Part of #5068, suggested by @ematipico and @MichaReiser, where @leaysgur
and I explored using biome formatter as the base and made a success. All
credits to the old Rome and the new Biome team.
This PR is in a boilerplate state where some of the functions are marked
as `todo!()`.
I also made the following changes:
* changed the base to be less generic, removed the `Language` and
`Context` generics
* expanded the formatter lifetime to include an `'ast` lifetime
* added access to the source text and comments
* added a mechanism for tracking and accessing parent ast nodes (done by
our codegen)
* removed most of the unit tests because they no longer compile
* removed the `oxc_prettier` crate
