fix: Lua dispatcher compat (#112)

* fix: temporary Lua dispatcher compat for workspace dispatchers

* fix(resizer): add Lua dispatcher compat for window resize/move/float/center

* feat(theme): write current.lua for Hyprland Lua config, current.conf for hyprlang

* fix: align gen_lua format with #111

* refactor address review feedback
refactor(hypr,theme): address review feedback

- cache is_lua_config result to avoid redundant socket calls
- remove is_lua_config wrapper, rename _is_lua_config to is_lua_config
- move hypr import to top of theme.py
- use single line syntax in apply_hypr and apply_colours

* restore original specialws behavior and some formatting
