Add version number to all command help outputs

- Created internal/version.go with Version constant set to "0.1.13"
- Updated all command help functions to display version in format "command v0.1.13"
- Modified commands: git-commitAll, git-evars, git-exec, git-list-executables,
  git-replicate, git-treeconfig, git-update
- Updated CHANGELOG.md for version 0.1.13

All commands now show their version in help output, making it easier to
verify which version is installed.

 - Fixed path condensation in `git-exec` command. Output now properly abbreviates paths using environment variable names
   (e.g., `$sites/project` instead of `/mnt/d/sites/project`).
+- Added version number to help output for all commands (displays as "v0.1.13" in command help text).
