[eas-cli] Add --dev-domain flag to eas deploy

[brentvatne]

Why

On a project's first eas deploy, the CLI interactively prompts for the preview URL subdomain (dev domain name). There is currently no way to provide it non-interactively, and when the server-suggested name is taken, non-interactive mode recurses forever in assignDevDomainNameAsync (it retries with the same taken name).

How

• New --dev-domain <name> flag on eas deploy: assigns the preview URL on first deployment without prompting.
  • Validated eagerly before any network call, sharing the interactive prompt's rules plus rejecting names the prompt would have silently auto-reformatted (formatDevDomainName(name) !== name).
  • If the requested name is taken → clear error.
  • If the project already has a different dev domain → clear error instead of silently ignoring the flag (the CLI has no path to change an existing dev domain).
• Fixed the non-interactive taken-name infinite recursion: both the flag path and the suggested-name path now throw actionable errors mentioning --dev-domain.
• New DeploymentsQuery.getDevDomainNameByAppIdAsync + regenerated GraphQL types (includes small unrelated schema-drift comments codegen picked up).

Test Plan

• yarn test src/worker/__tests__/deployment.test.ts — 19 new tests: validation rules, flag assignment without prompting, taken-name errors (flag + non-interactive suggested), existing-domain mismatch/match, full first-deploy retry flow.
• yarn typecheck, yarn lint, yarn fmt:check — clean.
• Smoke-tested via bin/dev: deploy --help shows the flag; --dev-domain 'My App!!' / 'ab' / 'ends-with-' fail fast with specific messages.

Manual:

• Fresh project: eas deploy --non-interactive --dev-domain my-fresh-name → assigns my-fresh-name.expo.app, no prompt.
• Taken name → "already taken, choose a different URL with the --dev-domain flag".
• Project with existing different domain → "preview URL is already set to … and cannot be changed".
