Worktree sync responses now branch on whether the client acknowledged the current commit, and add a readsStanding flag

What

When Claude Code syncs a git worktree (a checked-out copy of a repository) between a client and its session, the response now builds its history of applied changes (downApplied) differently depending on whether the client has already acknowledged the current worktree commit. If it has, the history folds in downstream applied changes on top of what was already sent; if not, it falls back to just the reversed sent history. The response also now always includes a new readsStanding flag set to true, alongside the existing acceptsHeldParents flag.

Why

This makes worktree sync responses more accurate for clients that haven't yet caught up to the latest commit, avoiding history that assumes acknowledgment that hasn't actually happened.
