The dashboard TUI Logs tab only showed the handful of lines emitted
through DashboardLogSink directly. Everything from @fusion/engine
(scheduler, executor, triage, merger, PR monitor, heartbeat, etc.)
logs via createLogger() which writes straight to console.error —
bypassing the sink. Under the TUI's alt screen those writes either
overdrew the frame or scrolled off, leaving the Logs tab near-empty.
DashboardLogSink now offers captureConsole() / releaseConsole():
while the TUI is running, console.log/warn/error are intercepted
and routed into the ring buffer. A leading `[prefix]` tag is
extracted so entries carry the subsystem name. Original console
functions are restored (by identity) on TUI shutdown.
