Add word wrapping mode (#3597)

* feat: add word wrapping mode for --wrap flag

* Run `cargo fmt` and add CHANGELOG entry

* Add word wrap tests, update manpage and shell completions

- Add integration tests for word wrapping: basic word boundary breaking,
  fallback to character wrapping for long words, line numbers, and
  short lines that fit without wrapping
- Update manpage to document the new 'word' wrapping mode
- Update bash, fish, zsh, and PowerShell completions with 'word' option
- Avoid unnecessary clone of `line_buf` when word wrap is disabled

* make clippy and cargo fmt happy

## Features
- Add word wrapping mode via `--wrap=word`, see #3597 (@veeceey)
- Implement `--unbuffered` mode for streaming input, allowing partial lines to display immediately (e.g. `tail -f | bat -u`). Closes #3555, see #3583 (@mainnebula)
- Added an initial `flake.nix` for a ready made development environment; see #3578 (@vorburger)
- Add `--quiet-empty` (`-E`) flag to suppress output when input is empty. Closes #1936, see #3563 (@NORMAL-EX)
