Make workspace, agent, and schedule automation consistent (#2186)

* feat(workspaces): align agent and schedule automation

Make workspace identity the shared placement boundary for MCP and CLI, while caller identity determines parentage. Keep heartbeats minimal and cron-based without changing legacy rolling interval semantics.

* test(cli): expect canonical schedule cadence

* fix(automation): preserve workspace and schedule compatibility

* fix(automation): preserve compatibility edges

* fix(workspaces): align MCP lifecycle resolution

* fix(workspaces): preserve creation intent

* fix(workspaces): preserve branch and schedule identity
