StageProjection.agent is pebble's fold of the stage's agent events, fed
every stored agent event before the fabro-only arms run. Every existing
field and arm stays for now. The parity tests prove each old field is
derivable from the embedded fold: the tree's usage, the route as the model,
the context window without fabro's stamped seq, the root's todo list, the
subagent rows, the skills, and the MCP servers under the disconnected,
error, ready rule.
