floating panel: always-on-top agent HUD with a global shortcut

a non-activating HUD panel (every Space, over full-screen apps, never takes
focus) listing the agents waiting for you, with working and idle summarized
on one line; rows jump to the agent, drag moves the panel and it remembers
its place. modes: when agents are waiting (default), always, off; ctrl+opt+
cmd+e shows or hides it on top of the mode, and a manual hide lasts until
another agent starts waiting. the shortcut is a carbon hotkey (no
accessibility permission; clashes are reported in the menu) configured in
~/.config/dingger/config.toml, reloaded on save. the menu bar app is split
into model, panel, hotkey and main.

tested: --selftest checks the visibility rules (it fails if a newly waiting
agent no longer re-shows a dismissed panel); e2e step 13 checks the panel
content through the real binary.
