调研方向

Start by locating the existing wsh command implementations and the controllerinput RPC using CommandBlockInputData. Trace how wsh commands connect through wave.sock and authenticate, then add the proposed text, enter, signal, and stdin input modes. Done means input reaches the selected terminal block through the existing RPC without requiring a hand-rolled client.

描述

Use case

I run a small external dashboard that watches my terminal blocks (via wsh blocks list + wsh termscrollback) and I'd like to also send keystrokes to a block — e.g. answer an interactive prompt in a long-running session from another machine/phone.

What exists today

The controllerinput RPC (CommandBlockInputData: blockid, inputdata64, signame, termsize) already does exactly this — the frontend uses it for all typing. It works great when called directly over wave.sock with the WAVETERM_JWT auth handshake (tested on v0.14.5, Windows). But there's no wsh subcommand for it, so scripts have to hand-roll the domain-socket RPC.

Proposal
wsh sendinput -b <blockid> "text to type"     # raw bytes to the pty
wsh sendinput -b <blockid> --enter            # append \r
wsh sendinput -b <blockid> --signal SIGINT    # signame variant

Reading input from stdin (wsh sendinput -b <id> -) would also cover binary/control sequences.

Related: #3196 (wsh tab rename), #3285 (wsh tab create) — same theme of making existing RPCs scriptable.
