v6.3.3: Merge PR #14 & #19, fix Windows errors, close issues

Merged PRs:
- PR #14 (@tenishevnikita): Fix project key encoding — use /[^a-zA-Z0-9-]/g
  to match Claude Code's encoding (fixes paths with underscores). Closes #16.
- PR #19 (@dimstunt): cmux proper Resume (new-workspace) and Focus
  (CMUX_WORKSPACE_ID env var) support.

Windows fixes (#15):
- Skip ps/grep process scanning on win32 (no ps aux on Windows)
- Add stdio:pipe to lsof calls to suppress error output
- Prevents mojibake error spam in PowerShell
