* fix(windows): read agent command lines without PROCESS_VM_READ Windows process command lines were read by opening each process with PROCESS_VM_READ and walking its PEB. Hardened runtimes (Electron/Node) and security products deny that access, so those processes resolved to a bare `node.exe`/`bun.exe` name with no argv, argv0, or cmdline. A runtime-wrapped agent launched from such a process was then indistinguishable from an unrelated runtime process, and the pane stayed on the shell with `agent_status: unknown`. Prefer `NtQueryInformationProcess` with `ProcessCommandLineInformation` (Windows 8.1+), which needs only `PROCESS_QUERY_LIMITED_INFORMATION`, and keep the existing PEB read as a fallback for processes that do not expose a stored command line. The fallback still requires `PROCESS_VM_READ`, so this only widens coverage. refs #4579 * fix(windows): handle growing command lines before failure test The retry added for a command line that grows between the size probe and the read was unreachable. NTSTATUS is signed, so STATUS_BUFFER_OVERFLOW, STATUS_BUFFER_TOO_SMALL, and STATUS_INFO_LENGTH_MISMATCH are all negative and were treated as failures by the earlier `status < 0` check. Check the growth statuses first and retry once with the reported size. Also read the returned UNICODE_STRING header unaligned, since a Vec<u8> buffer only guarantees byte alignment. * test(windows): keep command-line marker test process alive Passing the marker as a second argument to `ping` let `ping` exit as soon as it saw one target, so the command-line query could race the process exit. Move the marker into a `rem` after `&` so it stays in cmd.exe's own command line and `ping -n 11` keeps the process alive for the read.

the runtime your coding agents live on.
- detach without stopping work — herdr keeps terminals running in a background server when you close the client or lose your SSH connection. after a server or machine restart, herdr restores the saved layout and can resume supported agent sessions; the original processes do not survive. session state →
- several machines, one window — keep local work and saved ssh machines together, with a combined agent list and independent reconnects. remote machines →
- never hunt for the stuck one — every pane is marked working, blocked, or idle. when an agent stops and needs an answer, herdr says so.
- agent-native — agents drive herdr through the cli and socket api: they can spawn panes, prompt each other, and wait until another agent is genuinely blocked. agent skill →
- runs what you already run — claude code, codex, cursor, opencode, grok and the rest. herdr doesn't wrap or replace them; it owns their terminals.
- keyboard and mouse, both first-class — tmux-style prefix keys and click, drag, split. pick per moment, not per tool.
- plugins — extend panes and workflows. browse the marketplace →
- one rust binary, no electron — runs in whatever terminal you already use.
