fix: draft thread effectiveCwd fallback to project cwd and remove redundant ensureGitWorkspace

- buildLocalDraftThread now accepts projectCwd and falls back to it
  when no worktreePath is set, matching server-side projection logic
- Remove single-use ensureGitWorkspace helper and its redundant call
  in statusDetails (execute already guards via assertWorkspaceDirectory)
