feat!(terminal): unify terminal window behavior and centralize sizing config (#102)

- add terminal.window.type support (hsplit, vsplit, floating, tab)
- add terminal.window.split_size for split-based layouts
- rename floating size options to terminal.window.floating_width/floating_height
- validate terminal window ratios during setup
- make terminal.run/run_floating merge default keymaps internally
- remove cmd.split width/height sizing in favor of terminal.window config
- improve floating/log buffer state handling and refresh behavior
- update README examples and configuration docs

BREAKING CHANGE: terminal sizing/config moved to terminal.window.*.
Removed cmd.split.width/cmd.split.height.
Renamed terminal.window.width/height to terminal.window.floating_width/floating_height
