Fix project action failure with paths containing spaces

[taku25]

Description

Fixed an issue where Recent Projects in the Hyper theme would fail when project paths contain spaces. The Telescope action would not execute properly due to unescaped paths.

Changes

• Added vim.fn.fnameescape() to properly escape file paths containing spaces
• Applied escaping to lcd commands and project action string concatenation
• Ensures compatibility with paths that have spaces on Windows

Environment Tested

• Windows Terminal + PowerShell
• Paths with spaces in project directories

Before/After

Before: Project paths with spaces would cause action failures
After: All project paths are properly escaped and work correctly
