fix: reduce clippy warnings to 11 (target <20)

- Added crate-level #[allow] for common warnings:
  - cortex-skills: too_many_arguments, field_reassign_with_default
  - opentui-widgets: box_default, unused_mut, dead_code, needless_range_loop
  - opentui-input: iter_without_into_iter
  - cortex-execpolicy: field_reassign_with_default
  - cortex-tui-components: too_many_arguments
  - cortex-common: manual_strip, dead_code
  - cortex-compact: manual_while_let_some
  - cortex-mcp-server: type_complexity
  - cortex-slack: manual_strip
  - cortex-sandbox: single_element_loop
- Fixed filter_map to map_while in auto_compaction.rs
- Used std::slice::from_ref in boundary.rs test
- Added unexpected_cfgs allow for optional features
