fix: composer history, emoji search focus, usage ring, recap code, ask endings, invoke toasts, copy confirmation (#576)

- ↑/↓ browses past the newest message, and ↓ restores the mode before browsing (^541)
- the emoji picker focuses its search so typing filters instead of reaching the composer (^495)
- the usage ring sits above Send's hover halo so its center opens the popover (^571)
- recaps render backticked spans as code (^522)
- ace ask prints one ending for a stopped run (^592)
- only a missing provider key offers Providers on a failed invoke (^519)
- copying a message confirms with a toast (^566)
