Add controlled post_install/pre_start hook schema to AppDefinition:
LifecycleHooks/HookStep (Exec | CopyFromHost)/HostCopy with allowlist
validation (relative src, no '..', absolute container dest, non-empty
exec). Re-exported from the crate root. Design: docs/manifest-hooks-design.md.
Also add the missing generated_secrets: vec![] field to three
pre-existing ContainerConfig test literals (the field was added to the
struct in 03a4ee1b but the container crate's own tests were never rerun,
so -p archipelago-container failed to compile). cargo test green: 53 pass.
