protolabs42 0e5e9851d4 fix: move_dir fails across Docker volume mount points + call_plugin_hook crashes on missing plugin dir 
## move_dir (helpers/files.py)

`os.rename` fails with `OSError: [Errno 18] Invalid cross-device link` when
source and destination are on different Docker volume bind mounts (e.g.,
`/a0/tmp` and `/a0/usr` as separate named volumes). The current code catches
the exception with `except Exception: pass`, silently dropping the move.

This breaks plugin installation via the Plugin Hub — the cloned repo in
`/tmp/` never reaches `usr/plugins/` because the rename silently fails.

Fix: fall back to `shutil.move` on `OSError`, which handles cross-mount
moves by copy + delete.

## call_plugin_hook (helpers/plugins.py)

`find_plugin_dir(plugin_name)` can return `None` when called during
`run_install_hook` immediately after installation. Passing `None` to
`files.get_abs_path()` causes `TypeError: join() argument must be str,
bytes, or os.PathLike object, not 'NoneType'`.

This crashes the install hook, which triggers cleanup that deletes the
just-installed plugin directory, making the installation appear to fail
even though the clone and validation succeeded.

Fix: guard the `None` return and short-circuit with `default`.

## Reproduction

Deploy Agent Zero with per-directory volume mounts (as recommended in
docs to avoid volume shadowing):

```yaml
volumes:
  - a0-tmp:/a0/tmp
  - a0-usr:/a0/usr
  - a0-agents:/a0/agents
```

Then install any plugin from the Plugin Hub. Both bugs trigger:
1. `move_dir` silently fails (cross-mount rename)
2. `call_plugin_hook` crashes (plugin dir not found after failed move)
