fix: handle spaces and underscores in project paths

[Scoteezy]

Summary

• Fix project path generation to handle directories with spaces and underscores
• Added (space) and _ (underscore) to the character replacement regex in
  getProjectPath()

Problem

Directories with spaces or underscores in their names could cause issues with Claude
session file paths.

Solution

Extended the regex from /[\\\/\.:]/g to /[\\\/\.: _]/g to replace these characters
with hyphens.
