feat(cli): friendly missing-project status and per-project daemon state (#87)

- Block project-aware commands when ktx.yaml is absent and render a
  friendly "run ktx setup" message (plain or JSON) instead of leaking
  ENOENT or "Project: ..." noise.
- Make ktx status project detect the missing config and emit the same
  message via a shared renderMissingProjectMessage helper.
- Move the managed Python daemon state, stdout, and stderr files out of
  the shared runtime root into {projectDir}/.ktx/runtime so multiple
  projects no longer share a single daemon record.
- Simplify the runtime install root to ~/.ktx/runtime on every platform
  and split the daemon-specific paths into managedPythonDaemonLayout,
  threading projectDir through start, stop, and stop-all paths.
