feat(newos4): agent status says never-scheduled vs waiting; `guides` command (v4.6.63)

Packet 6 and 7.

6 — four agents showed `sleeping` and nothing distinguished "waiting for work" from
"never handed a task". Added tasksAssigned/lastTaskAt to the agent record (counted
where a task is actually assigned), and the status line now reads
  idle — NEVER SCHEDULED (0 tasks since 2026-10-23 16:22)
  idle — waiting for work (3 task(s), last 2026-10-23 16:22)
  parked — NEVER SCHEDULED ...
plus "Dispatch: 0/3 agent(s) have ever been given a task" and a warning that
spawning is not dispatching.

7 — /guides/ was reachable by nobody. New `guides` command lists it newest-first
with sizes and the preview/cat hints; help.html gained a Guides nav entry and
section with links to the published guides.

Verified live on v4.6.63: `guides` → 2 entries after seeding two files;
orchestrator-status shows 3x NEVER SCHEDULED on a fresh session (the packet's own
observation), and "waiting for work (3 task(s) ...)" once a counter is set, with
"Dispatch: 1/3".
