fix(agent-manager): make worktree hover cards instant

[marius-kilocode]

Worktree hover cards regressed to delayed open and close behavior after the prior speed-up fix. Restore zero-delay open and close behavior and remove the scoped worktree-card animations so hover details respond immediately again. The change is limited to Agent Manager worktree hover cards and includes a patch changeset.

SUGGESTION

File	Line	Issue
packages/kilo-vscode/webview-ui/agent-manager/WorktreeItem.tsx	191	closeDelay={0} leaves no tolerance for crossing the 8px gutter to reach the card's interactive controls; consider a small closeDelay with instant open

Files Reviewed (1 file changed since last review)

• packages/kilo-vscode/webview-ui/agent-manager/agent-manager.css - 0 issues (previous zero-duration animation suggestion is resolved: both [data-expanded] and [data-closed] now use animation: none, which lets Kobalte's presence unmount synchronously instead of waiting on an animationend that may never fire)

Notes / assumptions

• Incremental review of 7cfaeb2..6b5a605. Only agent-manager.css changed; the two animation: none overrides keep the same specificity as the base [data-component="hover-card-content"][data-closed] rule in packages/ui/src/components/hover-card.css and still win because agent-manager.css is bundled after @kilocode/kilo-ui/styles.
• The closeDelay suggestion on WorktreeItem.tsx:191 is unchanged in this push and remains open as an optional follow-up.
• No memory-leak or lifecycle concerns: CSS-only change, no new timers, listeners, or subscriptions.

File	Line	Issue
packages/kilo-vscode/webview-ui/agent-manager/WorktreeItem.tsx	191	closeDelay={0} leaves no tolerance for crossing the 8px gutter to reach the card's PR link and Remove-stale button; consider closeDelay={50} with instant open
packages/kilo-vscode/webview-ui/agent-manager/agent-manager.css	3290	Prefer animation: none over animation-duration: 0ms so Kobalte's presence unmount doesn't depend on a zero-duration animationend (stuck-card risk)

Files Reviewed (3 files)

• .changeset/instant-worktree-hover.md - 0 issues (user-facing wording looks good)
• packages/kilo-vscode/webview-ui/agent-manager/WorktreeItem.tsx - 1 issue
• packages/kilo-vscode/webview-ui/agent-manager/agent-manager.css - 1 issue

Notes / assumptions

• The PR description says the cards "regressed to delayed open and close behavior after the prior speed-up fix" and that this restores zero-delay behavior. History shows the delays went 100ms (a8d5af4) -> 50ms (909ec73) -> 0ms here, so this is a new behavior rather than a restoration; the description could be corrected. It also says the scoped animations were removed, but they are zeroed rather than removed.
• @kobalte/core is not installed in this environment, so the hover-card safe-area and presence-unmount behavior could not be verified directly; both suggestions are reasoned from the Kobalte 0.13.x hover-card/presence design and the shared styles in packages/ui/src/components/hover-card.css.
• Change is UI-behavior only; no memory-leak or lifecycle concerns introduced (no new timers, listeners, or subscriptions).
