feat: Add menuconfig abstraction framework with priority-based fallback

[Copilot]

Adds abstraction framework for menuconfig method selection with configurable priority ordering between graphical and terminal interfaces. Support for vscode-kconfig-visual-editor is temporarily commented out pending extension readiness.

Changes

Configuration

• Added smart.useTerminalMenuconfig setting to force terminal-only mode regardless of installed extensions

Core Logic (src/smart.ts)

• getMenuconfigMethod() implements priority-based detection framework: user preference → rt-thread-kconfig → (vscode-kconfig-visual-editor - commented out) → terminal
• MENUCONFIG_COMMANDS constants for extension command strings
• MenuconfigMethod interface for type-safe method selection
• vscode-kconfig-visual-editor detection logic commented out with TODO markers for easy future enablement

Integration

• Updated tree view menuconfig command (src/dock.ts) to use centralized detection
• Enhanced BSP context menu (src/project/cmd.ts) with extension-specific handling:
  • rt-thread-kconfig: Changes to BSP directory and executes command
  • Terminal fallback with error handling
  • vscode-kconfig-visual-editor handling prepared but commented out

Example Usage

const method = getMenuconfigMethod();
if (method.type === 'extension') {
    vscode.commands.executeCommand(method.command);
} else {
    executeCommand(method.terminal);  // scons --menuconfig
}

Current Priority Order

1. smart.useTerminalMenuconfig → terminal
2. rt-thread.rt-thread-kconfig → rt-thread-kconfig
3. vscode-kconfig-visual-editor (commented out, ready for future enablement)
4. No extensions → terminal scons --menuconfig

Status

The abstraction framework is complete and ready for use. Support for vscode-kconfig-visual-editor is implemented but commented out pending the extension's readiness. The code can be easily uncommented when the extension is ready to use.

This section details on the original issue you should resolve

<issue_title>feature: 也可以使用kconfig visual editor进行配置</issue_title>
<issue_description>新添加特性，在进行menuconfig时，如 vscode-kconfig-visual-editor 扩展已经安装了，则也可以使用 vscode-kconfig-visual-editor 进行配置。

• 当前是有两种方式：
  • 一种是使用 scons --menuconfig，是字符界面方式；
  • 一种是如果 rt-thread.rt-thread-kconfig 插件安装了，则使用 rt-thread.rt-thread-kconfig 插件；
• 希望做一定调整：
  • 先优先查看是否安装了 rt-thread.rt-thread-kconfig，如果安装了则使用 rt-thread.rt-thread-kconfig
  • 其次，会查看是否安装了 vscode-kconfig-visual-editor 插件，如果安装了则使用 vscode-kconfig-visual-editor;
  • 如果都没安装，则使用 scons --menuconfig。
• 同时在插件配置上有一个选项，是否只使用 scons --menuconfig 的方式。

在扩展中如涉及到其他的 menuconfig 也按照这样的方式进行，或者把上述过程抽象成函数。</issue_description>

<agent_instructions>按issue的方式进行修改，完善代码，并确保构建没问题，同时也处理好BSP（如果是workspace模式，则针对当前bsp或选择的bsp），Kconfig的问题。</agent_instructions>

Pull Request Overview

This PR implements support for the vscode-kconfig-visual-editor extension as an alternative method for menuconfig operations, with a configurable fallback hierarchy. The implementation adds a new configuration option to force terminal-based menuconfig and centralizes the extension detection logic into reusable utility functions.

Key Changes:

• Added a new smart.useTerminalMenuconfig configuration option to allow users to force terminal-based menuconfig
• Created centralized utility functions (getMenuconfigMethod()) to detect and select the appropriate menuconfig method based on installed extensions
• Updated menuconfig invocations in both tree view and BSP context menu to use the new prioritized detection system

Reviewed Changes

Copilot reviewed 4 out of 4 changed files in this pull request and generated 3 comments.

File	Description
package.json	Added smart.useTerminalMenuconfig boolean configuration option with bilingual descriptions
src/smart.ts	Added utility functions and constants for menuconfig method detection with priority ordering (rt-thread-kconfig → vscode-kconfig-visual-editor → terminal fallback)
src/dock.ts	Updated tree view menuconfig command to use the new getMenuconfigMethod() utility
src/project/cmd.ts	Enhanced BSP context menu menuconfig with special handling for each extension type and error recovery fallback

The error message 'Failed to open Kconfig file' is misleading because the rejection could come from vscode.window.showTextDocument() rather than opening the document. Consider a more accurate message like 'Failed to open or display Kconfig file'.

[Copilot]

The 'else' block at lines 64-68 is unreachable because the two preceding if conditions (lines 36 and 43) already cover all possible values of menuconfigMethod.command from MENUCONFIG_COMMANDS. This dead code should be removed or the logic should be restructured if additional extension commands are expected in the future.

Suggested change

	else {
	// Generic extension command
	executeCommand('cd ' + arg.fn);
	vscode.commands.executeCommand(menuconfigMethod.command!);
	}

@flyingcys 还麻烦帮忙review，谢谢。

@flyingcys 这里的扩展id对吗？谢谢

@copilot vscode-kconfig-visual-editor 还没完全ready，可以先对 vscode-kconfig-visual-editor 注释掉，保留现有的抽像框架。

@copilot vscode-kconfig-visual-editor 还没完全ready，可以先对 vscode-kconfig-visual-editor 注释掉，保留现有的抽像框架。

Done in commit a081765. The vscode-kconfig-visual-editor support has been commented out while preserving the abstraction framework. When the extension is ready, the code can be easily uncommented.

Changes made:

• Commented out vscode-kconfig-visual-editor detection in getMenuconfigMethod()
• Commented out vscode-kconfig-visual-editor handling in configProject()
• Added TODO comments for easy future enablement
• Addressed code review feedback: improved error message and removed unreachable code
