refactor(agent): stop sealing, shadowing and receipting each turn

Browse Source 
A turn no longer builds a shadow task contract, a completion report or a
sealed evidence bundle, takes a workspace snapshot, or hands the host a
completion receipt. Removes the agent-side producers and their wiring in boot,
the observation and verdict packages that only they used, and the
write-protection and unconfined-launch probes that only boot read.

The receipt and audit shapes on the event wire, the terminal and the desktop
settings stay for a later cleanup; nothing sends them now.
