chore: post-merge cleanup for agent integration fixes (#33644)

Post-merge cleanup after the agent-integration fixes: remove the unreachable Windows hook-script stdin drain epilogue; Windows statusline exits instead of draining outside an Orca pane; Codex CLI fork uses the \\?\-aware rollout path; WSL browser-network relay falls back to orcad's pinned Node (shared launcher revision stamp); stranded sleep records only drop for their own worktree; renames (hidden probe cwd, local Windows ConPTY helper).
