Issue body
The sequencer must keep track of layer state and changes in order to
emit actions related to the overlay step (such as layer reapplications
or re-execution of steps invalidated by changes in layers). Add a
layer state management helper to be used during the planning phase
to store the layer hash corresponding to each part and compute the
expected values to ensure overlay consistency.

| #119 overlay: add overlay hash to build and stage states (CRAFT-489) | craft-parts | merged | Merged pull request implementing overlay verification hashes in build and stage states to ensure proper step invalidation. Approved by two reviewers, passed CI checks, and successfully integrated. | |
| #115 overlay: add layer visibility helpers (CRAFT-477) | craft-parts | merged | Merged after two approvals. Introduces helper functions to extract migratable files and directories from overlay layers, correctly processing whiteout entries and opaque directories. The change adds 315 lines across three files. | |
| #138 many: handle layer reapplication (CRAFT-83, CRAFT-85) | craft-parts | merged | Merged changes handling layer reapplication to maintain overlayfs stack consistency during re-executed overlay steps. Approved by one reviewer, passed CI checks, and integrated by maintainer cmatsuoka across 20 files. | |
| #111 overlay: add overlayfs helpers (CRAFT-462) | craft-parts | merged | Merged. Added overlayfs mount and unmount helpers, plus utilities to identify special files and directories for filesystem layering. Approved by two reviewers, passed CI, and introduced 420 lines across six files. | |
| #116 overlay: compute layer validation hash (CRAFT-478) | craft-parts | merged | Merged after two approvals. Adds layer validation hash computation and persistence helpers. Author resolved a design concern by making the layer_hash argument mandatory and returning None for missing files, letting callers handle the absence. |
