G-061 notes: record 2026-07-19 console-context test-matrix findings

Three tests fail only under a half-attached console (stderr=console,
stdout=file): grepstr highlight tests emit empty SGR and nslist marking
loses its markers - punk::console process-global colour state under
mixed tty-ness. Fully-piped and -jobs runs green; fully-interactive
unverified. Recorded on G-061 (user direction) as a concrete
context-matrix workload for the pseudoconsole harness, alongside the
interim Start-Process selective-redirection repro technique and a
pointer to the related capture_stderr utf-16le fix (913ea749).
