This pull request introduces several changes to improve code consistency, enhance functionality, and add new features. Key updates include replacing string literals with a custom type for server names, implementing PID file management to prevent duplicate instances, and adding prompts for various functionalities. Additionally, there are updates to dependencies and refactoring for better modularity.

Code Consistency and Refactoring:

• Replaced string literals for server names (e.g., BrowserServerName, CommandServerName) with the MoLingServerType custom type for better type safety and consistency. ([[1]](https://github.com/gojue/moling/pull/29/files#diff-d28c280801f4a5ac525d036ee232b3823a6bdf7c800c3127cea2a2c1ef8e9d37L35-R36), [[2]](https://github.com/gojue/moling/pull/29/files#diff-255513b4527fd7bbbf2e847c570842c03e574d5974694b8ee056e8bc44a3def3L38-R38))
• Updated logging and service initialization to use string() conversions where necessary for compatibility with the new type. ([[1]](https://github.com/gojue/moling/pull/29/files#diff-d28c280801f4a5ac525d036ee232b3823a6bdf7c800c3127cea2a2c1ef8e9d37L59-R60), [[2]](https://github.com/gojue/moling/pull/29/files#diff-255513b4527fd7bbbf2e847c570842c03e574d5974694b8ee056e8bc44a3def3L64-R64))

New Features:

• Added PID file management in mlsCommandFunc to prevent duplicate instances of the server. This includes creating and removing the PID file and handling timeouts during shutdown. ([[1]](https://github.com/gojue/moling/pull/29/files#diff-eb154bbd601602eeae895e7af6a12b88cbdb7d585a2d32216c398f68cabcdff5R170-R178), [[2]](https://github.com/gojue/moling/pull/29/files#diff-eb154bbd601602eeae895e7af6a12b88cbdb7d585a2d32216c398f68cabcdff5L222-R283))
• Introduced new constants such as MLPidName for PID file naming and updated MLROOTPATH to MLRootPath for consistency. ([[1]](https://github.com/gojue/moling/pull/29/files#diff-eb154bbd601602eeae895e7af6a12b88cbdb7d585a2d32216c398f68cabcdff5L70-R73), [[2]](https://github.com/gojue/moling/pull/29/files#diff-eb154bbd601602eeae895e7af6a12b88cbdb7d585a2d32216c398f68cabcdff5L80-R83))

Dependency Updates:

• Upgraded github.com/mark3labs/mcp-go to version v0.21.0 and updated other indirect dependencies for compatibility. ([go.modL7-R14](https://github.com/gojue/moling/pull/29/files#diff-33ef32bf6c23acb95f5902d7097b7a1d5128ca061167ec0716715b0b9eeaa5f6L7-R14))

Prompt Additions:

• Added detailed multilingual prompts for filesystem, browser, and command-line management to enhance user interaction. These prompts include structured instructions and capabilities for each functionality. ([[1]](https://github.com/gojue/moling/pull/29/files#diff-a34fe2c7669aa7fa6704860ed53b72e0998d9a84a61834f18d7e0b73411e0aeaR1-R69), [[2]](https://github.com/gojue/moling/pull/29/files#diff-4814356be1692906e394cdce7da9138d1f1207710e60e8c24e584fd2764b766bR1-R76), [[3]](https://github.com/gojue/moling/pull/29/files#diff-2a0847855513aab7412e8b56a153cb95993999ee896d00682c3838bdb1e387b3R1-R83))

Utility and Modularization:

• Refactored directory creation functions to use the utils package instead of services for better modularity. ([[1]](https://github.com/gojue/moling/pull/29/files#diff-1da78e247fa9e1955df2583ffcaaa486a6b59c5375b7659cb98c47167da4b9e1L20-R32), [[2]](https://github.com/gojue/moling/pull/29/files#diff-d28c280801f4a5ac525d036ee232b3823a6bdf7c800c3127cea2a2c1ef8e9d37L76-R86))
• Removed unused or commented-out code to clean up the implementation, such as unused logger hooks in the browser server. ([[1]](https://github.com/gojue/moling/pull/29/files#diff-d28c280801f4a5ac525d036ee232b3823a6bdf7c800c3127cea2a2c1ef8e9d37L76-R86), [[2]](https://github.com/gojue/moling/pull/29/files#diff-d28c280801f4a5ac525d036ee232b3823a6bdf7c800c3127cea2a2c1ef8e9d37L475-R476))
