Extend the DeploySearch action to accept additional parameters for
configuring the project search from keymaps:

- query: prefilled search query string
- regex: enable regex search mode
- case_sensitive: match case exactly
- whole_word: match whole words only
- include_ignored: search in gitignored files

With this change, the following keymap becomes possible:

```json
["pane::DeploySearch", { "query": "TODO|FIXME|NOTE|BUG|HACK|XXX|WARN", "regex": true }],
```

Release Notes:

- Added options to `pane::DeploySearch` for keymap-driven search
