Pure sync-action computation shared by all file-transfer platforms.
Compares local and remote file maps and returns a list of actions:
{:push, relative_path}— local is new or newer{:pull, relative_path}— remote is newer{:delete, relative_path}— remote-only file (when delete enabled)
Local map: %{relative_path => %{size: integer, mtime: integer}}
Remote map: %{relative_path => {size, mtime}}
Public for testing (see AGENTS.md "Public API Seams").
Summary
Functions
Computes sync actions from local and remote file maps.
