Why

Use the session's saved private/public choice for worker preview links and the simulator's Share button. Part of ENG-28070.

How

• Read public_preview for all five iOS session types. Older jobs without the field keep their public behavior.
• For private sessions, pass --disable-share, omit --share-url, and print the authenticated website link supplied by WWW.
• For public sessions, keep the public link and native Share button.
• If a private link is missing, report it as unavailable. Keep preview URLs and tokens in remote config so the website can connect.
• Redact preview tokens from host startup and recording failure diagnostics.

Release serve-sim #336 first, then this worker change, then WWW #32347. CLI #4619 builds on this PR.

Agent use

Gabe directed the behavior and reviewed the final changes. Codex wrote the code, tests, and description. At Gabe's request, the worker passes flags directly without version probing. Independent source review found no blocker.

Test Plan

Codex ran all 275 tests across the eight affected build-tools suites after rebasing, plus production typecheck and full repository lint/format. Independent source review found no further runtime defects. Release notes use the current changeset format. Hosted validation of the saved preference remains pending.

Earlier local launch validation ran Universe-generated steps through build-tools download, install, and start on a real iOS Simulator. It checked one app start, launch arguments, and the deep link, with a pinned local serve-sim build and loopback adapters for cloud tunnel/reporting calls. CI and hosted EAS testing are separate.

ENG-28070

[gwdp]

Codex implemented the build-tools sharing inputs, direct serve-sim flags, and private-link logging under Gabe’s direction, then removed the version probe and its tests at Gabe’s request.

eas-cli now uses changesets for changelogs (#4580). The required "Check for a changeset" check fails on PRs that edit CHANGELOG.md.

To update this PR:

1. Revert the changes to CHANGELOG.md.
2. Run yarn changeset, select the changed packages and the bump type, and write the summary.
3. Commit the new file in .changeset/.

The release adds the PR link and the author to the entry. If this PR needs no changelog entry, revert the CHANGELOG.md changes and add the "no changelog" label.

Codex rebased this PR onto main 4ec2a5f, preserving the new serve-sim startup flow, worker REST authentication, and ngrok token isolation. Conflict cleanup updates the test token arguments and converts the release note to the required changeset format. No intended sharing behavior changed.

All 275 tests in the eight affected build-tools suites, production typecheck, full lint/format, and changeset validation pass. Independent source review found no remaining runtime regression.
