Module migrations 

One-time / self-idempotent migrations for agent session zones.

Submodules are pub so every public item (stat structs, marker consts) is reachable as agent_session::migrations::<submod>::<item>. The two migration entry points are additionally re-exported here (and again from the parent) to preserve the flat agent_session::migrate_* call sites.

Re-exports

pub use v1_blocks::block_zones_look_incomplete;

pub use v1_blocks::migrate_block_zones_v1;

pub use v1_blocks::MIGRATION_MARKER_V1;

pub use v1_templates::migrate_promote_template_sessions_v1;

Modules
