v1.3.0

• The picker creates, it never switches. Inside tmux the new-session
  picker now lists every running session — the one you are in on top, marked
  ▌, with the cursor on it — and Enter on a running session starts
  another Claude Code session in that session's directory instead of jumping
  back into it (jumping is the sidebar's job). ^S still opens a terminal
  there, and Tab now names the new session on running-session rows too.
  So prefix+N Enter is "one more Claude Code here".
• Names follow the directory on every row, -2, -3, … past taken ones: a
  third agent in ~/dev/suite1 is suite1-3, never suite1-2-2.
• Fixed: since 1.0.0 the picker dropped the session it was opened from, which
  left no row for its directory at all — no way to open a terminal or a
  second agent where you already are.
• Outside tmux (bare pier) Enter on a running session still attaches to
  it: without a sidebar, that is the way back into a session.
