* fix: restore terminal pgrp after PATH lookup Snapshot the terminal foreground process group before the shell PATH probe in ShellCommandLocator.runShellCommand and restore it on return, so `watch` sessions keep TTY foreground ownership and Ctrl+C keeps working after CLI commands. Block SIGTTOU on the calling thread across the restoring tcsetpgrp: the restore runs from a background process group (the probe shell moves the terminal foreground and the post-completion kill(-pgid) cleanup strands it), where the default SIGTTOU action would otherwise stop the CLI. * fix: harden terminal foreground restoration * fix: preserve newer terminal foreground jobs * fix: restore redirected terminal ownership * fix: harden terminal foreground recovery * fix: recover dead terminal descendant groups * fix: reject unrelated terminal foreground groups * fix: isolate interactive PATH probes * fix: define detached spawn flag on Linux * fix: support detached probes on Linux * test: gate detached session proof to Linux * fix: restore terminal pgrp after PATH lookup Snapshot the terminal foreground process group before the shell PATH probe in ShellCommandLocator.runShellCommand and restore it on return, so `watch` sessions keep TTY foreground ownership and Ctrl+C keeps working after CLI commands.
