fix(types): satisfy pyright strict on the refactored facades

Two facade issues from the reorg:

  * orchestrator/__init__.py used `__all__ = list(_LAZY)`, which pyright
    strict can't analyze (reportUnsupportedDunderAll) — and because it
    isn't a static literal, the TYPE_CHECKING re-export imports read as
    unused. Replaced with the explicit literal list the other lazy
    facades already use.
  * manifest/index.py imported six piece types (ManifestAgentProvider,
    EGRESS_AUTH_SCHEMES, ManifestEgressConfig/Route, ManifestGitEntry,
    ManifestKeyConfig) it never referenced — the package facade re-exports
    those straight from their submodules, so index.py needn't import them.
    Dropped the dead imports.

pyright: 0 errors (was 24). Full unit suite green (2243).
