/**

* Format a version string for display with exactly one leading "v".
|

|
|
*
|
||
|
|
* Version strings reach the UI from several sources — manifests (bare like
|
||
|
|
* "1.7.96"), node/federation state and the update RPC (sometimes already
|
||
|
|
* "v1.7.96"). Templates used to hard-code a `v` prefix (`v{{ version }}`),
|
||
|
|
* which produced "vv1.7.96" whenever the source already carried a "v". This
|
||
|
|
* normalizes both shapes to a single "v".
