Rewind 0.2.7

Rewind 0.2.7 fixes the repeated Steam save authorization is invalid or expired error during online launch.

• Validates the saved Steam connection with the current server before syncing MyCAREER or joining the queue.
• Opens normal Steam sign-in when the server rejects the old connection. The refreshed account must match the Steam account open on the PC.
• Clears rejected sign-in credentials even if the new sign-in is cancelled, so Retry can recover. Network timeouts preserve the saved connection and local progress.

Keep the 0.2.6 operator running. This is a launcher update; no new server package is needed. The required game update introduced in 0.2.6 remains in place, and existing game update receipts and saves are retained.

Only the launcher executable is published here. Players on 0.2.5 or 0.2.6 can use the launcher updater. Players on 0.2.3 or 0.2.4 should download this executable directly, close the old launcher, and replace its portable executable once.

Validation: all 351 launcher checks and 22 server authentication checks passed. The packaged interface reported no renderer errors. The rejected-session recovery was tested with isolated fixtures; no live game session was launched by this release process.
