refactor(cli): let the emitter report the output tail it leaves behind
Two places believed they owned terminal output: consume_stream streams
assistant deltas live while emit_output = true, and run_turn decided
whether to emit a separating newline before spinner.finish by guessing
from final_assistant_text(&summary).
That guess agrees with reality only because every *other* writer happens to
terminate its output with a newline — tool results go through
stream_markdown (which appends one), thinking summaries are written with a
trailing newline, and tool-call headers use writeln! — so the assistant
text path is the only one that can leave a partial line. That is a property
of the current renderers rather than of the streaming protocol, and it is
not enforced anywhere.
TerminalTail is state the emitter records into as it writes: both live
writers (AnthropicRuntimeClient::consume_stream and the tool-result blocks
in CliToolExecutor::execute) now push bytes through a TailTrackingWriter
that reports the last byte written, and the caller that ends a turn asks
where the emitter stopped instead of inferring it.
The heuristic also left the failure arm unguarded. A turn that streamed text
and then errored called spinner.fail on a partial line, which the line
clear then erased; that arm now carries the same guard.
Also gate the animated spinner.tick frame on is_terminal(). That frame is
pure cursor control (save, rewrite line, restore) and emits no newline, so
down a pipe it leaves an unterminated banner that the first streamed delta
then continues on the same physical line.
