[C]: Bump react-relay from 16.2.0 to 19.0.0

[dependabot]

Bumps react-relay from 16.2.0 to 19.0.0.

Release notes

Sourced from react-relay's releases.

v19.0.0

Version 19.0.0 Release Notes

Relay 19.0.0 includes many documementation improvements, bug fixes, and improved capabilities.

@alias required on conditional fragments

To improve type safety, the @alias directive is now required on all fragments that are only conditionally fetched either due to @skip/@include or fragment type conditions which only conditionally match. You can opt out of this validation on a per-fragment basis with the @dangerously_unaliased_fixme directive.

To enable incremental migration we include a codemod which will automatically add the @dangerously_unaliased_fixme in all required places:

npx relay-compiler codemod mark-dangerous-conditional-fragment-spreads

You can also opt out of this validation entirely via compiler config feature flag:

{
  // ...
  "featureFlags": {
    "enforce_fragment_alias_where_ambiguous": {
      "kind": "disabled"
    }
  }
}

Improved Docs

We've merged ~30 commits to clean up and improve our docs since the last release:

• Added new pages:
  • Quick Start - A single page guide to get Relay up and running locally
  • Production Setup - A list of best practices for setting your Relay application up for production use cases
  • Relay Babel Plugin - Information about Relay's Babel plugin and how to install it in your app.
  • Relay Environment - API docs for the core Relay environment
  • Runtime Configuration - Documentation covering runtime feature flags and more
• Removed outdated or orphaned doc pages
• Streamlined and fixed issues in existing docs

React 19 Compatible

React 19 is now a valid peer dependency of Relay (#4944) by Krzysztof Karol (commit)

Breaking Changes

• Relay now defaults to generating ES module imports in its generated js files. You can add "eagerEsModules": false in your relay.config.json to opt back into the old behavior. (commit)
• Relay's NPM modules nolonger include a pre-bundled module. (#4935) by Iha Shin (commit)
