Issue body
The overlay manager is used to mount the overlay stack during the execution
of the overlay step (or the build step for parts with overlay visibility) and perform
overlay package installation. This commit implements mount operations, package
installation will be added in a separate changeset.

| #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. | |
| #135 executor: add overlay step handling (CRAFT-86) | craft-parts | merged | Merged. Adds overlay step handling to the executor, mounting the overlay stack during builds so parts with overlay visibility can access the filesystem for package installation and user scripts. Approved and passed CI. | |
| #297 overlay: only refresh overlay packages if necessary | craft-parts | merged | Merged an optimization that skips mounting and refreshing the overlay package cache unless a part uses overlay-packages, avoiding unnecessary expensive operations. Approved, passed CI, and changed three files. | |
| #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. | |
| #113 overlay: add overlay support to parts (CRAFT-470) | craft-parts | merged | Merged after three approvals. Adds overlay support to parts by defining the work directory and properties for overlay subdirectories and visibility. 149 additions, 37 deletions across six files. Removed Final typing hint for Python 3.7. | |
| #134 overlay: add overlay package install (CRAFT-81) | craft-parts | merged | Merged. Adds overlay package installation by executing maintainer scripts in a chrooted environment to correctly update the package database. Approved by two reviewers, with clarifications added on pychroot usage and empty file safety. | |
| #1190 fix(overlay): detect conflicts between overlay and install | craft-parts | merged | Merged fix enhancing Stage step collision detection to account for overlay contents, preventing conflicts with install directories. Includes integration tests, passed all CI checks, and received approval from three reviewers. | |
| #121 overlay: migrate overlay data to stage and prime (CRAFT-468, CRAFT-82) | craft-parts | merged | Merged after two approvals and CI. Migrates overlay data to stage and prime, translates overlayfs whiteouts and opaque directories to OCI, and cleans shared areas. Collision detection is deferred. | |
| #137 many: add overlay step (CRAFT-84) | craft-parts | merged | Merged. Adds an overlay step to process filesystem mutations like package installation and file modifications across parts. Updates multiple subsystems and tests, approved by a reviewer, passed CI, and maintains fast execution. | |
| #143 lifecycle_manager: check if overlay is supported (CRAFT-562) | craft-parts | merged | Merged implementation adds overlay support verification to the lifecycle manager. The update validates Linux OS and superuser privileges before overlay execution. Approved by one reviewer, passed CI, and modified seven files. |
