Supported Patch Deletions

PR-022 adds an explicit deletion plan for the supported patch replay result:

prikk checkout --patch-delete-plan [path] [--ref REF]

It also adds an opt-in materialization mode that removes eligible files:

prikk checkout --patch-materialize-delete [path] [--ref REF]

Deletion is intentionally narrow. Prikk deletes only files that the replayed patch chain removed with a DeleteFile operation. Before removing a worktree file, Prikk checks that the current file bytes still match the operation’s old Blob precondition.

Safety boundaries:

• Arbitrary untracked files are never deleted.
• Modified deleted files are refused.
• Symlink targets and non-file targets are refused.
• General checkout pruning remains deferred.
• Text edits, renames, chmod, symlinks, merge conflicts, inverse logic, and full patch algebra remain later increments.
