fix(maestro): tool icon left of diff stat on sidebar meta line

Meta line fragment order was command last, after the blocked-work diff
stat, so the tool icon sat right of the diff count instead of left.
Reorder to duration/detail/command/diff-stat in both web and TUI
sidebars per docs/SIDEBAR.md, and update the contract doc + TUI tests
to match.

+space nesting already reserves for indentation. The rail paints for every
+card, `Idle` included, and is independent of whatever line 2 has to say; a
+card with nothing else to report still shows its rail next to the bare
+command. `<duration>` follows in the rail's colour when shown. There is no
+state word and no second badge: the rail exists so the state is still legible
+when a row is dimmed or the terminal renders the duration in the default fg.
+
+In the **web client** the rail is a 5px bar positioned inside the row's own
+indent gutter — it shifts outward with nesting depth exactly as the gutter
+does — spanning the full card height. It carries motion, reserved for states
+that need attention (DESIGN.md's "living signals" rule): a slow breathing
+opacity while `Active`, a hard blink while `AwaitingInput`, a fast flash while
+`Error`. `Idle` is solid and still, on purpose. `prefers-reduced-motion`
+leaves every state as a solid bar.
+
+In the **TUI** the rail is a one-column-wide block glyph (`▌`) in the state's
+palette role, leading the existing indent gutter (`INDENT`/`META_INDENT`) on
+both the name row and the meta row, so the two lines read as one continuous
+bar. Folder headers gain a matching blank leading column so labels still
+align under session names. The TUI has no render cadence to animate against,
+so its rail is always static — colour is the whole signal there, as it
+always was.
+
+Either client's rail carries the accessibility duty the old inline dot did:
+it is the element whose `title`/`aria-label` names the state, so status still
+never relies on colour alone.
