Crash: sync.data.lsp is undefined when sidebar renders LSP panel

[Echoziness]

Bug Description

Opening the sidebar with the LSP panel crashes the TUI with:

TypeError: undefined is not an object (evaluating 'sync8.data.lsp.map')

Root Cause

In packages/opencode/src/cli/cmd/tui/plugin/api.tsx:186:

lsp() {
  return sync.data.lsp.map((item) => ({ id: item.id, root: item.root, status: item.status }))
}

Unlike other methods in the same file that use ?? [] for fallback:

message(sessionID) { return sync.data.message[sessionID] ?? [] }
permission(sessionID) { return sync.data.permission[sessionID] ?? [] }
question(sessionID) { return sync.data.question[sessionID] ?? [] }

The lsp() method has no null guard. When the sidebar renders the LSP panel before the LSP service is initialized, sync.data.lsp is undefined, causing the crash.

Reproduction

1. Open a project in opencode TUI
2. Trigger LSP diagnostics on a file (e.g., open a C/C++ file with clangd)
3. Open the sidebar before LSP service finishes initializing
4. Crash occurs

Environment

• opencode version: 1.3.9
• OS: Windows 11
• LSP: clangd

Suggested Fix

Add null guard in api.tsx:186:

lsp() {
  return (sync.data.lsp ?? []).map((item) => ({ id: item.id, root: item.root, status: item.status }))
}

Same pattern should be applied to mcp() at line 189 if sync.data.mcp can also be undefined.
