* chore: migrate to Rust 2024 edition and bump to v0.9.2
- Bump edition to 2024 and rust-version to 1.85.0
- Replace f64::log10 with usize::ilog10 in num_digits
- Fix clippy lints surfaced by edition bump: repeat_n, derived Default, then_some
- Expand watch-check and watch-test aliases to cover all feature paths (crossterm_0_28, no-backend, tuirs variants, serde, arbitrary)
- Expand CI test and clippy workflows to full 6/8-entry feature matrices including termion on Ubuntu
- Apply rustfmt import reordering from edition 2024 rules
* fix: revert turis linux checks
* select, second go using new multiline code
* implemented internal delete_str, added tests
* delete_str_internal must not put non deleted strings into history. Ie ctrlc should not change history
* delete_str was taking lines out in the non delete case
* corrected comment
* fixes after feedback. Plus multichar bugs. change modal sample
