feat(maestro): add maestro send for typing into a session

Adds POST /api/sessions/:id/input and a CLI command on top of it, so a
script (or another agent) can hand an instruction to a running session
without attaching to it.

The text goes in as one write and the Enter follows 150ms later: agents
that run a full-screen prompt coalesce a burst of input into a paste, and
a newline inside that burst becomes a line break instead of sending the
message. `--no-enter` skips the Enter and leaves the text in the prompt.

The session argument takes an ID, a unique ID prefix, or a session name;
names win over prefixes. A session whose pane has exited is refused (409)
rather than silently accepted — unlike a stray keystroke on an attach
socket, a send that goes nowhere is worth hearing about.

 forced kill removes it as usual — force changes what happens to blocked work,
 not ordinary cleanup.
 
+In the web client the kill button sends the unforced `DELETE` straight away —
+there is no pre-confirmation, because the daemon is the one that decides. Only
+the refusal raises a prompt, and that prompt names what is in the way and offers
+"Force kill", which repeats the request with `force=true`.

 Ending a session and destroying its work are two separate acts. Maestro only
 performs the first one. Removing a tree it left behind is the operator's own
 `git worktree remove`, chosen while looking at exactly what would be lost.
