initializeTracking method

void initializeTracking()

A no-op, and deliberately still called.

Every diff reads the controller's live state directly, so there is no private tracking state to seed: a sync controller created against a populated TreeController, or one whose tree was mutated behind its back, already diffs against the controller's actual state. The method survives as the hook callers invoke after (re)creating a sync controller, so an implementation added later needs no new call site.

Implementation
