When no agent is selected, `e` / `p` do nothing (status line
shows "no agent selected") rather than falling back to today's
global discover-and-prompt. The discover-and-prompt scaffolding
in `_operator_edit_routes_flow` / `_operator_edit_allowlist_flow`
comes out entirely — selection in the agents pane is now the
only way to scope an edit. Old open-question #4 (single-bottle
shortcut behavior in proposals-pane mode) is moot and removed.
Draft a PRD that adds an "active agents" pane to the dashboard
TUI (below the existing proposals pane) and reshapes the operator
`routes edit` (e) / `pipelock edit` (p) verbs to be agent-scoped
when the cursor is in the agents pane — no more global discover
+ disambiguation prompt on every press. Tab toggles which pane
nav keys move through.
Sized into 4 chunks (discovery helper → render pane → selection
state → agent-scoped verbs). Six open questions called out, the
biggest being whether per-bottle `compose ps` on every 1s tick
scales for hosts with many bottles (answer leans toward one
label-filtered `docker ps`).
