Agent PBX v0.5.0

Highlights

• Adds richer Files tab image previews in the TUI with truecolor ANSI
  half-block rendering, grayscale text fallback, built-in PNG decoding, and GIF
  first-frame decoding.
• Adds optional image decoding support through agent-pbx[images] for Pillow,
  plus a best-effort chafa fallback when the binary is installed on the host.
• Improves tmux direct mode by tracking tmux streaming per selected agent, so
  one agent can use the tmux stream while another stays on the standard PBX
  latest report view.
• Adds cached @path completion in the Latest input and tmux direct input from
  directories already read in the Files tab.
• Adds /ctrlc support for sending Ctrl+C through tmux direct mode, useful for
  backing out of Codex /side chat.
• Expands TUI and workflow test coverage around file browsing, path completion,
  tmux mode selection, and image preview rendering.
