Team mode shares one disk per Space. RPC and executor paths under
bots/<otherBotId>/ were reachable with any member-owned entry bot,
leaking another member's workspace files while same-user cross-bot
access stays intentional.
Add path guards, filter bot listings, regression tests.

and drop the coordinator reply silently. Retry instead, and block
clearThread while completed bot_message runs still owe a return.
