* feat: add per-pane default foreground/background color support
Add per-pane default foreground and background colors, configurable
through four surfaces:
- OSC 10/11 escape sequences (set/query) and OSC 110/111 (reset)
- CLI action: zellij action set-pane-color --pane-id <id> --fg/--bg
- Layout config: default_fg/default_bg properties on pane nodes
- Plugin API: set_pane_color() SDK function and PaneInfo read-side
Colors are applied at render time as a fallback when cells have no
explicit foreground/background, without mutating stored grid data.
Closes#4712
* refactor: address review feedback for pane color support
- Extract adjust_styles_for_custom_bg_fg in output/mod.rs
- Move color parsing (xparse_color) from tab into Grid
- Move color serialization (ansi_code_to_color_string) into Grid
- Pane trait now uses Option<String> for color getters/setters
- Add colors to session serialization (dump-layout)
- Add default_fg/default_bg to protobuf IPC schema to fix
layout-in-session color loss
- Update example layout with tab-bar and status-bar
* fix stack overflow and ordering
* rustfmt
* update e2e snapshots

* adjust example layouts and move them from `./example` to
`./example/layouts`
* simplify the deserialization of the layout
* layouts are now constructed as follows:
```
