* 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
`e`'s behavior is actually not same as `w`. For example, let's say we
have the following text and the cursor is on 'f'.
```
foo bar
```
Then `de` deletes the text 'foo' but `dw` deletes the text 'foo '
including the trailing space.
Vim's text selection is inclusive. For example, when a cursor is on 'r'
of 'bar', 'r' is included in the selection. However tui-textarea's text
selection is exclusive on the end of the range. Move cursor forward to
emulate Vim's behavior better.
