Subject: [PATCH] feat: add automatic workspace detection based on file path

Automatically switches to the appropriate workspace when opening markdown files based on their file path. This eliminates the need to manually switch workspaces when working across multiple vaults.

The plugin now sets up an autocommand that runs on BufEnter and BufRead events for *.md files, detecting which workspace the file belongs to by matching the file path against configured vault paths.
