[Resume] opened a "bash" session and typed `claude --resume <id>` into it.
The tab's session type is what the Shift+Enter binding keys off, so in a
resumed conversation Shift+Enter submitted the prompt instead of inserting
a newline. The status-bar hint and Send to agent missed those tabs too.
open_terminal_session now takes an optional resume_session_id and launches
`claude --resume <id>` through the normal Claude path (update prelude,
permission flags, Bedrock SSO check). `-n` is dropped when resuming so the
tab label ("resume" when the conversation has no name) does not rename the
conversation. resume_session_command and its capability grant are removed.
