Still investigating why.. 

### **Issue: `OMARCHY_PATH` and `PATH` for omarchy/bin missing after omarchy-update**

**Description:**

Following an `omarchy-update`, the `$OMARCHY_PATH` environment variable appears to be missing, which causes subsequent update attempts and other `omarchy` commands to fail. Manually exporting `OMARCHY_PATH` and adding `$OMARCHY_PATH/bin` to the system's `$PATH` in `~/.bashrc` resolves the issue. This suggests that the update process may be interfering with the shell environment configuration.

**Steps to Reproduce:**

1. Run `omarchy-update` on a functioning `omarchy` installation.
2. After the update completes, open a new terminal session.
3. Attempt to run `omarchy-update` again.

**Expected Behavior:**

The `omarchy-update` command should execute successfully without any modifications to the user's `.bashrc` file. The `$OMARCHY_PATH` variable and the path to the `omarchy` binaries should be correctly set in the shell environment.

**Actual Behavior:**

The `omarchy-update` command fails with a "command not found" error for `omarchy-update-git`, as shown in the logs below. This is due to the `$OMARCHY_PATH` variable being unset.

**Error Logs:**

```

**Workaround:**

The issue was resolved by adding the following lines to `~/.bashrc`:

```bash
# added
export OMARCHY_PATH=~/.local/share/omarchy
export PATH=$OMARCHY_PATH/bin:$PATH
```

After sourcing the updated `.bashrc` or opening a new terminal, `omarchy-update` functions as expected.

**Successful run after applying the workaround:**

```bash
omarchy on  master [✘]
❯ export OMARCHY_PATH=~/.local/share/omarchy

omarchy on  master [✘]
❯ echo $OMARCHY_PATH
/home/shk/.local/share/omarchy

**System Information:**

*   **OS:** Arch Linux (as implied by the `omarchy` context).
*   **Shell:** bash

**Additional Context:**

The user reported that other users have experienced the same issue. This indicates it's likely a recurring problem and not an isolated incident. The issue seems to stem from how the `omarchy-update` script handles shell environment variables, potentially overwriting or failing to preserve them across its execution.
