feat: streamline opencode loading screens and reuse the reload flow for vscode Restart API

Loading screens: drop the internal-jargon progress text on the opencode
reload overlay (ConfigUpdateOverlay) and the vscode init splash — show
text only on errors. Replace it with a glow pulse on the OpenCode mark on
the cube's top face; OpenChamberLogo's isAnimated prop was a no-op and now
actually animates. vscode shows the glow on the inline splash logo and the
React app stops writing 'Loading data (… Providers, … Agents)…'.

Restart API: 'OpenChamber: Restart API Connection' now runs the same full
reload flow used after an OpenCode update — the command asks the chat
webview to call reloadOpenCodeConfiguration() (overlay + managed restart
via the bridge + config/data refresh) instead of a bare manager restart,
falling back to the old restart when no webview is open. Mounts
ConfigUpdateOverlay in the vscode app so the overlay actually shows there.
