v0.3.3

Added

• dev repo cd <repo> provides shell-only repository navigation, equivalent
  to dev repo open <repo> --runtime none, including argument completion and
  the shell wrapper's directory handoff. It never opens a multiplexer.

• REMOTE can expand a repository into on-demand GitHub PR/GitLab MR pages,
  inspect checks and diffnav previews, and open an exact task-free worktree or
  independent Try clone. Large repositories default to authored/requested-review
  requests; navigation never preloads PR lists or details.

• dev pr view, diff, checkout, merge --squash, and sync-base share the
  dashboard services. Squash merge binds the reviewed head and retains unknown
  outcomes without retries; optional base sync uses guarded fast-forward or
  explicitly chosen rebase, with separate partial results and no local cleanup.

• REPOS/REMOTE offer Open in gh-dash for verified GitHub repository targets,
  including uncloned REMOTE rows, while retaining native gh-dash configuration.

• A reproducible, isolated worktree workflow trial compares Herdr with no dev
  task record against Sidecar workspaces. The guide documents task-free cleanup
  and sharing dev repo list --json with optional project navigation adapters;
  existing task commands and JSON contracts remain unchanged.
