Instead of bailing when children have duplicate filesystem names,
syncback now resolves collisions by appending incrementing suffixes
(e.g. Foo, Foo1, Foo2). This handles both init-renamed children and
any other name collisions. Meta stem derivation is now path-based
to correctly handle collision suffixes and dotted names.

When a child instance has a Roblox name that would produce a filesystem
name of "init" (case-insensitive), syncback now automatically prefixes
it with '_' (e.g. "Init" → "_Init.luau") instead of erroring. The
corresponding meta.json writes the original name via the `name` property
so Rojo can restore it on the next snapshot.
The sibling dedup check is updated to use actual on-disk names for
existing children and the resolved (init-prefixed) name for new ones,
so genuine collisions still error while false positives from the `name`
property are avoided.

Adds a CLI flag that forces syncback to use JSON representations
instead of binary .rbxm files. Instances with children become
directories with init.meta.json; leaf instances become .model.json.
