Only --json was taken after the command, so `wait --paused --timeout
60s`, the order the guide's own synopsis and agents use, failed with
"unknown argument '--timeout'", and `-i` after the command did too.
And since that --json was taken as the output flag, `call X --json
'{...}'`, the documented way to pass arguments as JSON, never reached
call: its object then failed as "not key=value".
--timeout, -i and --json now go anywhere on the line; no command has
options of those names. After `call`, a --json followed by an object
is the arguments, and any other --json the output flag. A trailing
--timeout or -i without its value is a usage error that says so.

debug.log handed `last` to the timeline query, where 0 means every
entry, so `log --follow --last 0` streamed the whole ring of up to 8192
entries before the new ones, where an agent reads it as tail -n 0 -f:
nothing old, only what comes next. 0 now means no backlog, followed or
not, and the guide says that --follow starts with the last 50.

Cli::Run is the whole client but its transport, so tests run it in
process against a real Session; main will hand it the QUIC connection.
- Commands: ls, status, cmds, help, call, get, set, pause, resume,
step, wait, trace, log (with --follow), screenshot, quit, debugger,
guide and version, with -i, --json and --timeout.
- call types key=value from the command's argument schema (slot=1 is
a number, name=1 a string, at.x=3 nests), so agents need no JSON
for simple calls; a value that cannot fit its field is a usage
error before anything is sent.
- The instance comes from discovery; one running instance needs no -i.
The record's protocol is checked before any request: a mismatch
exits 4, says which side is newer and prints the app's own client.
Other sources only warn.
- A request with no reply is diagnosed: the app has exited, stopped
in a debugger (with the attach command), or no longer calls Pump
(with what to change). Exit codes: 2 usage, 3 no instance,
4 version, 5 timeout, 6 the app's error.
- Output is short by default, arrays cut at 20 with a note; --json
prints everything. `guide` is the full reference for agents.
