Make undo tracking opt-in

[TrystonPerry]

Undo recording now defaults to disabled for document and collection hooks and their shared subscriptions, with explicit resource-level opt-in via undoable: true. Regression tests cover the disabled default and enabled behavior, while documentation and the React tasks example are updated for the new contract. Bumps the package version to 0.1.7. Validation: pnpm test, pnpm typecheck, pnpm build, and the React tasks example build.

Note

Make undo tracking opt-in for useDocument and useCollection hooks

• Changes the default value of undoable from true to false in useDocument, useCollection, and the underlying shared subscription factories in src/core/shared-subscription.ts and src/react/hooks.ts.
• Resources must now explicitly pass undoable: true to their hook call to enable undo tracking; individual writes can still skip undo with a per-call undoable: false.
• Updates the React Tasks example app to opt in where needed and adds tests verifying undo is not recorded by default.
• Behavioral Change: any existing hook usage that relied on undo being enabled by default will silently stop recording undo actions after this update.

🟡 Medium src/App.tsx:197

TaskListBody uses useTaskListView(PARAMS, { readOnly: true }) without undoable, so it overwrites the shared collection's undo flag to false after AddTaskForm sets it to true. When the list is empty there are no TaskRow instances to reset the flag, so adding the first task is not recorded in undo history and cannot be undone. Pass undoable: true here as well, or make read-only consumers leave the shared undo setting unchanged.
