fix(agent-manager): open terminal when switching worktrees

[marius-kilocode]

An open Agent Manager terminal panel currently becomes an empty state when switching to a worktree that has not created a terminal yet, forcing an extra click before the panel is useful again.

Keep the panel active across worktree switches and ensure the selected context has a side terminal. Existing terminals are reused, and the existing pending-create guard prevents duplicate terminals during rapid switching.

WARNING

File	Line	Issue
packages/kilo-vscode/webview-ui/agent-manager/terminal/side.ts	114	!previous combined with { defer: true } swallows the first context switch — Solid's on doesn't record prevInput on the deferred run, so the first worktree switch after mount still shows the empty terminal state

SUGGESTION

File	Line	Issue
packages/kilo-vscode/webview-ui/agent-manager/terminal/side.ts	115	Auto-create leaves a live PTY/websocket in every context the user passes through; side terminals are never reclaimed on context switch
packages/kilo-vscode/webview-ui/agent-manager/AgentManagerApp.tsx	1873	Effect flushes synchronously inside selectWorktree, and showSideTerminal() also clears history/review — races the per-context review restore and closes the history view
