Problem

The UI sidebar currently shows a version string (e.g. 0.1.4 (8db0acc)) which is actually the my_hypervisor version, not hero_compute's. There's no way to see which versions of the stack components are running.

Objective

Display the running hero_compute version (with git hash) in the sidebar, and show all component versions on hover.

Requirements

Sidebar version display

Show hero_compute <version> (<git_hash>) as the primary version in the sidebar
This should come from the running binary's version, not a hardcoded string

When hovering over the version, show a tooltip with all component versions:

hero_compute     0.1.6 (abc1234)
my_hypervisor    0.1.4 (8db0acc)
hero_proc        0.4.4
cloud-hypervisor v50.0.0
mycelium         0.7.3

Implementation Notes

Backend (`hero_compute_ui/src/server.rs`)

The existing /version endpoint returns version info — extend it to include all components
For each component, shell out to <binary> --version (or version for my_hypervisor) and capture the output

Return as structured JSON:

{
  "hero_compute": "0.1.6 (abc1234)",
  "my_hypervisor": "0.1.4 (8db0acc)",
  "hero_proc": "0.4.4",
  "cloud_hypervisor": "v50.0.0",
  "mycelium": "0.7.3"
}

Components not found should show not installed

Frontend (`static/js/dashboard.js` + templates)

Fetch /version on page load
Display hero_compute version in the sidebar version area
Add a CSS tooltip (or Bootstrap popover) on hover showing all component versions
Use monospace font for the tooltip for alignment

Git hash for hero_compute

Embed the git hash at compile time using env!("GIT_HASH") or a build.rs that captures git rev-parse --short HEAD
The workspace currently doesn't have this — needs to be added

Acceptance Criteria

Sidebar shows hero_compute 0.1.x (hash)
Hover tooltip shows versions of: hero_compute, my_hypervisor, hero_proc, cloud-hypervisor, mycelium
Missing components show not installed
Version info updates on page refresh
