Summary

• drain pending ACP session metadata updates before returning session commands/options
• wait for in-flight ACP client startup instead of treating Starting as connected
• isolate ACP slash command picker from BitFun local commands, clamp long descriptions, and keep keyboard selection scrolled into view

Testing

• pnpm run fmt:rs
• cargo check -p bitfun-acp
• cargo test -p bitfun-acp
