SeedHost v0.6.6-alpha — initial publication timeout fix

SeedHost v0.6.6-alpha

Unsigned portable Windows prerelease. Update both hosting PCs; keep independent world backups.

Fixes

• Initial group Start now gives the owner's safely stopped initial publication up to two minutes instead of applying the five-second control-reply deadline. Ordinary control deadlines remain unchanged. Expiry never authorizes takeover or launch on uncertain custody.
• Concurrent Playit status polling no longer mistakes a tunnel still being created for a missing or changed saved route. Completed bindings retain their route validation and cancellation safeguards.

Verified scope and limits

Real isolated pinned-TLS regressions reproduce delayed initial publication and the Playit setup/status race. The initial-publication tests verify latest bytes, a single running holder, bounded expiry and no late member launch. Playit fixtures exercise setup polling and changed-route rejection without real provider credentials.

This does not certify different-network Minecraft gameplay or arbitrary modpacks. Automatic group launch retains its validated Vanilla/Fabric JAR-layout limits. Public Playit approval and reachability remain separate checks. Worlds, friends and hosting groups do not need to be deleted for this update.
