What to build

A filmmaker can undo and redo authored edits, and can open several windows on one Project that stay in sync. Project settings edits are the first undoable commands. Later tickets plug their authored edits into the same log. Locking, queuing, rendering, generating and importing never go into it.

Acceptance criteria

ProjectSession holds an in-memory, per-Project command log with undo/redo for authored edits
Project settings edits (title, aspect ratio) can be undone and redone
Append-only operations are documented as not undoable, and the log has no way to record them
Every state change broadcasts a coarse changed { kind, ids } event to all windows, and views refetch
A second window on the same Project can be opened inside one process sharing one ProjectSession, and an edit in one window shows in the other
Tests cover undo/redo through ProjectSession and that a change event is emitted for each edit
