Consolidate CLI and server machine defaults under settings.toml,
including loader renames, writer preservation fixes, same-machine
manifest handling, and docs/test updates for the new config model.
Move durable run access and execution control onto the server-backed client,
canonicalize run APIs under /api/v1/runs, and switch CLI integration tests
to a shared test daemon/storage model with shared-state-safe assertions.
Replace in-process workflow E2E hook tests with fabro-cli workflow
integration tests that run fabro as a subprocess and pass OpenAI twin
env only to the child process. Remove the unsafe env-var mutation helper
from fabro-workflow integration tests.
