v0.28.0-beta.5

Delta since previous beta (v0.28.0-beta.4) — 2 new changesets.

Minor Changes

• Add manual rename to terminal tabs. Double-click a terminal tab (or press F2
  while it's focused) to give it a name of your own, edited inline. The custom
  name pins over whatever title the running program sets via its terminal title
  escape sequence — useful for agent CLIs that constantly rewrite their title — so
  the tab keeps the name you chose. Press Enter or click away to commit, Escape to
  cancel; committing an empty name clears the custom label and restores the
  program's title (or the positional "Terminal N" default).
