Summary

Bring the current v14.0.0 branch into beta so the next beta ships the latest v14 work. This follows the refresh pattern of #440 and #449.

What this brings into beta on top of 14.0.0-beta.3:

• feat!: safe, consistent --json error documents #461: safe, consistent --json error documents, quiet spinners under JSON output, jsonSuppressedBy, --prompt rejected under --json, and credential redaction with @heroku/js-blanket 1.4.0 CREDENTIAL_PATTERNS.
• Main-line catch-up from rebasing v14.0.0 onto main: dev dependency bumps (@types/node 26.6.6, serialize-javascript ^7.1.4).

#457 (fall back on native store misses) changed src/credential-manager-core/, which v14 removed in #448, so it is not in this refresh. @heroku/heroku-credential-manager 0.2.1 already treats macOS and Windows misses as absent credentials. The Linux D-Bus search and locked-item handling still need to be ported to that package.

Only four files differ from v14.0.0: package.json and package-lock.json keep the version 14.0.0-beta.3, and release-please-manifest.beta.json and CHANGELOG.md are kept from beta. All other source is v14.0.0 verbatim.

The feat(beta) title is the Conventional Commit that makes Release Please propose 14.0.0-beta.4, so no separate trigger PR is needed. Merging publishes nothing; the Release workflow on beta does.

Testing

Notes: The source is v14.0.0 with only the beta version metadata kept.

Steps:

1. git diff --stat origin/v14.0.0 origin/eb/refresh-beta-from-v14-beta3 lists only package.json, package-lock.json, release-please-manifest.beta.json and CHANGELOG.md.
2. grep '"version"' package.json and .github/release-configs/release-please-manifest.beta.json both show 14.0.0-beta.3.
3. After merge, run the Release workflow on beta with dry_run=true and check that the release PR proposes 14.0.0-beta.4, with feat!: safe, consistent --json error documents #461's changes in its changelog.
