refactor(manifest): break import cycle by extracting ManifestBottle to a leaf module

manifest.py imported the extends/loader resolvers, while those resolvers
needed ManifestBottle back from manifest.py — a true bidirectional cycle
papered over with in-function imports and TYPE_CHECKING guards (not clear
dependency inversion).

Extract ManifestBottle into a new leaf module manifest_bottle.py that depends
only on the other leaf modules (manifest_util/agent/egress/git/schema).
manifest.py re-exports ManifestBottle, so `from .manifest import ManifestBottle`
callers are unaffected. With the cycle gone:

- manifest_extends and manifest_loader import ManifestBottle from
  manifest_bottle and their other deps from the real source modules, all at
  top level (TYPE_CHECKING block removed).
- manifest.py imports the extends/loader/schema/yaml_subset/log helpers at
  module top; all per-function lazy imports in the cluster are removed.

No behavior change; full unit suite green, pyright clean.
