this is to allow commands like below, which opens a file for quick edits
from jjui:
```toml
[custom_commands.open_file]
key = ["O"]
lua = '''
local file = context.file()
if not file then
    flash("No file selected")
    return
end
exec_shell("vim " .. file)
'''
```

ps: i tried using `os.execute` but it wouldn't return to jjui after vim
exits. hence exec_shell function is exposed via lua.

### Release Notes

#### 🆕 Features

##### Lua Scripting Enhancements

- **Lua Context Module** ([#&#8203;465](idursun/jjui#465)): Added context module to Lua scripting API, exposing methods for accessing selected item metadata and checked items:
  - `context.change_id()` - Get the change ID of selected revision or file
  - `context.commit_id()` - Get the commit ID of selected revision, file, or commit
  - `context.file()` - Get the file path of selected file
  - `context.operation_id()` - Get the operation ID of selected operation
  - `context.checked_files()` - Get array of checked file paths
  - `context.checked_change_ids()` - Get array of change IDs from checked items
  - `context.checked_commit_ids()` - Get array of commit IDs from checked items
- **Shell Execution in Lua** ([#&#8203;471](idursun/jjui#471)): Exposed `exec_shell()` function to Lua scripts, enabling interactive commands like opening files in external editors directly from jjui. This enables custom commands such as:
  ```toml
  [custom_commands.open_file]
  key = ["O"]
  lua = '''
  local file = context.file()
  if not file then
      flash("No file selected")
      return
  end
  exec_shell("vim " .. file)
  '''
  ```

#### ✨ Improvements

- **Abandon Workflow**: Removed confirmation dialog; users can now use Space to add/remove revisions from the abandon list

#### 🐛 Bug Fixes

- **Preview Pane Scrolling** ([#&#8203;472](idursun/jjui#472)): Fixed broken Ctrl-U/Ctrl-D scrolling in the preview pane that was introduced by earlier input routing changes. Preview commands are now properly grouped and always handled.
- **Parser**: Fixed handling of divergent change ID format
- **Bookmarks**: Fixed tracking of new bookmarks (currently tracks all remotes)

#### 🔧 Compatibility

- **Jujutsu 0.36.0 Support** ([#&#8203;407](idursun/jjui#407)): Updated commands to work with breaking changes in Jujutsu 0.36.0:
  - Changed `--destination` flag to `--onto`
  - Changed `--edit` flag to `--editor`
  - Removed deprecated `--allow-new` flag from `git push` commands
  - Updated keybinding from `d` to `o` for `--onto` flag in related modes

#### 📝 Documentation

- **README Updates** ([#&#8203;470](idursun/jjui#470)):
  - Added missing op log revert item to help menu
  - Fixed redo documentation
  - Updated custom command examples
