Remove the deployed sha plain-text badge from the card head.
Add a forge-linked menu item to the three-dot menu instead:
'deployed:abc123def012 ↗' opens agent-configs/<name>/commit/<sha>
on the hive forge in a new tab.
Only shown when both c.deployed_sha and forgeBase are present.
buildAgentMenu now takes forgeBase as second arg; call site passes
the same forgeBase computed for nav-strip links.
CSS: add text-decoration: none + box-sizing to .agent-menu-item
so <a> link items render identically to the <button> items.
