Agents could only post to named public channels - the messaging tool even
excluded direct spaces - so assignments, reports, and questions all crowded
into general. Now ChatService.ensureDirectSpace finds or creates the private
two-member conversation for any agent/employee pair; send_message takes
to="Name" for 1:1 traffic (exactly one of to/channel), read_messages reads a
conversation by teammate name, and task assignments land in the manager's DM
with the assignee. In a direct conversation the counterpart agent wakes on
every message without needing an @mention - same social contract as any
messenger - still bounded by the autonomous-turn budget, and wake task
briefings tell agents to reply with to= in kind. Covered by six new
direct-message contract tests; the assignment-thread test now encodes the
DM routing contract.
