Fix/nested cwd server handling

[shuv1337]

Fixed server failures when starting from deeply nested directories by changing process.cwd() to home directory at startup.

Added process.chdir(Global.Path.home) in serve and web command handlers to establish stable working directory Updated server middleware fallback from process.cwd() to Global.Path.home for consistency Added comprehensive regression tests validating the fix across multiple scenarios The fix prevents "No such file or directory" errors that occurred when the server process's working directory became invalid or was deleted
