Stefan Vetter 79de65a8f5 feat: implement per-mode MCP server/tool filtering
Adds granular per-mode control over which MCP servers and tools are available, replacing the previous all-or-nothing 'mcp' group behavior.

Schema (packages/types/src/mode.ts): - Add mcpServerFilterSchema with disabled/allowedTools/disabledTools - Add mcpDefaultPolicy ('allow'|'deny') for deny-by-default support - Add mcpGroupOptionsSchema extending group options for MCP tuples - Add superRefine validation rejecting MCP options on non-mcp groups

Core filtering (src/utils/mcp-filter.ts): - getMcpFilterForMode() resolves MCP config for a mode - isMcpServerAllowedForMode() checks server access with policy - isMcpToolAllowedForMode() checks tool access with allowlist/blocklist - Inlined getGroupName to avoid vscode import chain (ISSUE-16)

Prerequisite fix (src/utils/mcp-name.ts): - Fix normalizeForComparison regex: /[-\s]+/g -> /[-\s]/g (ISSUE-10) - Add toLowerCase() for case-insensitive matching

Prompt-level filtering: - filter-tools-for-mode.ts: Filter MCP tools from system prompt - build-tools.ts: Filter MCP tools for Gemini native function calling - ISSUE-19: Document native tools remain unfiltered for Gemini

Execution-time guards: - validateToolUse.ts: Replace blanket MCP allow with filter checks   - Server-level guard for use_mcp_tool/access_mcp_resource   - Tool-level guard for dynamic mcp--server--tool names   - ISSUE-21: Tool-level check for use_mcp_tool when tool_name available - presentAssistantMessage.ts mcp_tool_use: Add filter using cline.taskMode - ISSUE-17: validateToolUse call uses cline.taskMode (frozen at task start)   instead of state.mode (live UI mode) - ISSUE-20: Remove dead ?? defaultModeSlug fallback

Defense-in-depth: - UseMcpToolTool.execute(): Server + tool level filter before execution - AccessMcpResourceTool.execute(): Server level filter before execution - FLAG-E: Document 10-second TTL cache in CustomModesManager

UI fix (webview-ui): - ModesView.tsx: Cache group tuple options on toggle-off, restore on   toggle-on to prevent MCP config data loss (ISSUE-9/ISSUE-13) - Extract pure caching functions to groupOptionsCache.ts
