fix(i18n): use 工作树 consistently for parent worktree strings in zh locale (#16954)

* feat: select parent worktree for nesting when creating workspace

Enable users to pick a parent workspace in the composer's Advanced drawer,
organizing newly created worktrees hierarchically in the sidebar. The backend
validates lineage relationships and gracefully retries without the parent if
it becomes unavailable during creation.

* feat: select parent worktree for nesting when creating workspace

- Record app-picked parents as manual actions, not CLI-flag equivalents,
  ensuring the same user action carries consistent cleanup semantics across hosts
- Gracefully retry without parent if the selection goes stale, warn the
  user instead of failing
- Refactor create into modules: parent resolution, payload building,
  state merge

* Allow selecting parent worktree when creating workspace

- New parent worktree picker filtered by execution host and project
- Preserve concurrent local writes to lineage by comparing per-record state instead of key-set membership

* Allow selecting parent worktree when creating workspace

- Rename "Parent workspace" label to "Parent worktree"
- Filter candidates by execution host and project to prevent nesting across hosts
- Wire parentWorktreeId through composer state and creation request pipeline
- Update translations and add new copy for nesting-related messages

* fix(i18n): use 工作树 consistently for parent worktree strings in zh locale

Addresses PR #15420 review feedback: parent worktree strings mixed
工作区 (workspace) and 工作树 (worktree) terminology.
