feat(cloud): Maestro deprecation — drop legacy hard-block, soft-warn 1.39.5/1.41.0

[finalerock44]

What

Replaces the legacy Maestro removed-versions hard-block with a soft deprecation warning for the versions slated for removal.

• Removes REMOVED_MAESTRO_VERSIONS = ['1.39.1','1.39.2','1.39.7','2.0.3','2.4.0'] and its throw new CliError(...) — no longer needed.
• Adds a non-fatal warning for 1.39.5 and 1.41.0 (sunset 26 June 2026 per the docs; upgrade to 2.6.0+). These still run during the grace period.

Rendered via the same ui.warn + ui.branch layer as the iOS 16 notice:

⚠ Maestro 1.39.5 is deprecated
  ⎿ Maestro 1.39.5 will be removed on 26 June 2026; after that, tests pinned to it will fail.
    Upgrade to Maestro 2.6.0 or above.
    See: https://docs.devicecloud.dev/configuration/maestro-versions

Notes

• Fires only when the resolved Maestro version is one of the deprecated set; non-fatal (warnOut → suppressed under --json).
• The existing --maestro-version 1.39.5 integration test still passes (the run submits as before, now with an added warning).
