I dug out the old soft wrapping code and adapted for the new ultraviolet package that came with bubbletea v2.

I’ve removed viewport from the diff view and replaced it with uv.ScreenBuffer and uv.StyledString, which gives us built-in wrapping.

The diff now has two explicit modes: a normal no-wrap mode and a wrapped mode.

  • When entering wrapped mode, we precompute the soft-wrap layout data and then keep it in sync with width changes, so scrolling and bounds remain accurate.
  • Rendering in wrapped mode is done directly into the visible view area via StyledString. Wrap can be toggled with w in the diff view.

fixes #565

drop `viewport` and use `render` package instead

this also adds soft wrapping using `uv.StyledString`

### Release Notes

<details>
<summary>idursun/jjui (idursun/jjui)</summary>

### [`v0.10.0`](https://github.com/idursun/jjui/releases/tag/v0.10.0)

[Compare Source](idursun/jjui@v0.9.12...v0.10.0)

Wow, a major release after a very long time. As promised, `v0.10` is ready, and it comes with **breaking changes**.

First, thank you to everybody who contributed code, bug reports, ideas, and testing for this release. In particular, thanks to [@&#8203;baggiiiie](https://github.com/baggiiiie) for various features and fixes, [@&#8203;nickchomey](https://github.com/nickchomey) for contributions and continuous feedback, and [@&#8203;vic](https://github.com/vic) for updating the documentation website. Thanks as well to everyone else for various code contributions, reporting issues, and verifying fixes.

We changed a lot in `v0.10`, but the biggest shift is that we finally got rid of some **legacy configuration** and moved to a unified **actions + bindings** model. Old concepts like `[custom_commands]` and `[leader]` are now replaced by a more consistent system built around **actions**, **bindings**, and first-class support for leader-style key sequences.

This release also introduces `config.lua`, which makes it much easier to customise and extend `jjui` with **real scripting** instead of only static configuration. Between `config.toml`, `config.lua`, Lua actions, and bindings, much more of the UI can now be customised in one consistent way.

The documentation has been updated with [**migration notes**](https://idursun.github.io/jjui/migrating/v0_10/) and examples such as the [**Lua Cookbook**](https://idursun.github.io/jjui/lua-cookbook/).

From my testing it looks ready, but I am sure more rough edges will show up once more people start using it, so please keep reporting issues as you find them.

#### ⚠️ Breaking Changes

`v0.10` replaces the **legacy keybinding and customisation model** with the new **actions + bindings** system.

- `[keys]` configuration is no longer used.
- `[custom_commands]` is replaced by `[[actions]]` and `[[bindings]]`.
- `[leader]` sequences are replaced by sequence bindings via `seq`.

If you have an existing configuration, plan to **migrate it** rather than expecting a drop-in upgrade from `v0.9.x`.

#### ✨Highlights

- **Unified actions + bindings system.** Keyboard input now flows through a single dispatch pipeline, default bindings are declared in TOML, actions are discoverable, and custom behaviour can be defined in both TOML and Lua.
- **Much stronger scripting support.** Lua `setup` now receives the full config plus runtime context, generated intent-backed actions replace handwritten drift-prone bridges, and new helpers like `wait_close()` and `wait_refresh()` make multi-step scripts more predictable.
- **Upgraded TUI foundations.** Moving from **Bubble Tea v1** to **v2** brings better terminal support, a new rendering engine for better performance, and better input handling, including support for bindings like `ctrl+space` and dedicated `shift+...` style keys.
- **Improved diff and selection workflows.** The `diff` view now supports word wrap, `revisions` and `details` support modifier-based mouse selection, and several `details` and `evolog` interactions are more consistent.

#### 🚀 New and Improved

##### Command History

- Added [**command history**](https://idursun.github.io/jjui/command-history/), available with `shift+w`, to review dismissed command runs together with their output.
- Moved **running command** information out of the status area and into dedicated `flash` messages, so the command and its output are now shown together in one place.

##### Help and Status

- Reintroduced a dedicated **Help view** for full keybinding discovery, with filtering and scrolling, alongside the existing inline help.
- Changed **status/help** binding presentation to **column-major order** so related bindings are easier to scan.

##### Lua and Configuration

- Shipped the unified **actions + bindings** architecture introduced in `v0.10`.
- Exposed the full config object to Lua `setup`, including runtime context such as repository path via `config.repo`, and terminal state via `config.terminal.dark_mode`, `config.terminal.fg`, and `config.terminal.bg`.
- Standardised closeable action naming around `open_*` and aligned apply/close semantics for more predictable scripted workflows.

##### Oplog

- Added **quick search** to `oplog` and shared the search behavior with revision search.

##### Evolog

- Changed `evolog` preview defaults to show **interdiff** output, matching `jj evolog -p` more closely.

##### Abandon

- Added `s` in `abandon` mode to target descendants of the selected revision(s).

##### Revset

- Kept `revset` editing open when the expression is invalid, improving iteration while editing.
- Improved `revset` editing so function completion inserts `(` when appropriate, while the function list display is cleaner and less noisy.

##### Diff

- Added **word wrap** in the `diff` view, with explicit wrapped and unwrapped modes plus soft-wrap-aware scrolling.
- Added `g` and `G` in the `diff` view to jump to the top and bottom.

##### Details and Revisions

- Added `Ctrl+click` single-item toggle and `Alt+click` range selection in `revisions` and `details`.
- Added a `revisions.details.select_file` action for finer control in `details` workflows.

#### 🛠️ Fixes

- Fixed rendering issues with **double-width characters**.
- Simplified divergent revision handling by using `change_id/offset` directly from the `jj log` prefix template.
- Fixed `git push --all` behaviour for deleted bookmarks and corrected related command descriptions.

#### ⚙️ Internal Updates

- Upgraded to **Bubble Tea v2**.
- Replaced remaining `cellbuf` usage with `ultraviolet`.
- Hardcoded model-level key handling has been removed in favor of dispatcher-driven intents.
- Continued internal cleanup around rendering, overlays, display context, and generated action plumbing to support the new architecture.
