fix(sandcastle): revert idle timeout to 300s and remove redundant copyToWorktree

The 600s timeout was a misguided workaround for serena MCP init. The actual
root cause is an opencode bug: zero stdout during its git check-ignore
indexing phase. Removing copyToWorktree since pnpm install in onSandboxReady
already handles node_modules via the mounted pnpm store.
