Commit Message

feat(printer): Implement four-channel output model (#519)

Implements RFD 048, separating JP's output into four distinct channels:
stdout for assistant responses, stderr for chrome (tool headers,
progress indicators), `/dev/tty` for interactive prompts, and a log file
for tracing.

`Printer` gains a `PrintTarget::Tty` variant backed by `/dev/tty` on
Unix and `CONOUT$` on Windows. A new `prompt_writer()` method routes
interactive prompts to the TTY when available, falling back to stdout.
All tool renderers, retry notifications, and reasoning progress
indicators are moved to `err_writer()`, keeping stdout clean for
assistant output that downstream consumers can pipe or capture reliably.

Tracing is now written to a log file by default and suppressed on stderr
unless explicitly requested via `-v` or `--log-file=-`. This keeps `2>
chrome.log` free of tracing noise. A new `--log-file` flag supports
directing logs to an alternate destination, with `--log-file=-`
restoring the previous behavior of logging to stderr.

Closes: #518
