## Summary
- Adds a new `/statusline` command to configure TUI footer status line
- Introduces reusable `MultiSelectPicker` component with keyboard
navigation, optional ordering and toggle support
- Implement status line setup modal that persist configuration to
config.toml
## Status Line Items
The following items can be displayed in the status line:
- **Model**: Current model name (with optional reasoning level)
- **Context**: Remaining/used context window percentage
- **Rate Limits**: 5-day and weekly usage limits
- **Git**: Current branch (with optimized lookups)
- **Tokens**: Used tokens, input/output token counts
- **Session**: Session ID (full or shortened prefix)
- **Paths**: Current directory, project root
- **Version**: Codex version
## Features
- Live preview while configuring status line items
- Fuzzy search filtering in the picker
- Intelligent truncation when items don't fit
- Items gracefully omit when data is unavailable
- Configuration persists to `config.toml`
- Validates and warns about invalid status line items
## Test plan
- [x] Run `/statusline` and verify picker UI appears
- [x] Toggle items on/off and verify live preview updates
- [x] Confirm selection persists after restart
- [x] Verify truncation behavior with many items selected
- [x] Test git branch detection in and out of git repos

Codex created this PR from the following prompt:
> upgrade this entire repo to Rust 1.89. Note that this requires
updating codex-rs/rust-toolchain.toml as well as the workflows in
.github/. Make sure that things are "clippy clean" as this change will
likely uncover new Clippy errors. `just fmt` and `cargo clippy --tests`
are sufficient to check for correctness
Note this modifies a lot of lines because it folds nested `if`
statements using `&&`.

* #2467

This PR:
* Added the clippy.toml to configure allowable expect / unwrap usage in
tests
* Removed as many expect/allow lines as possible from tests
* moved a bunch of allows to expects where possible
Note: in integration tests, non `#[test]` helper functions are not
covered by this so we had to leave a few lingering `expect(expect_used`
checks around
This PR overhauls how active tool calls and completed tool calls are
displayed:
1. More use of colour to indicate success/failure and distinguish
between components like tool name+arguments
2. Previously, the entire `CallToolResult` was serialized to JSON and
pretty-printed. Now, we extract each individual `CallToolResultContent`
and print those
1. The previous solution was wasting space by unnecessarily showing
details of the `CallToolResult` struct to users, without formatting the
actual tool call results nicely
2. We're now able to show users more information from tool results in
less space, with nicer formatting when tools return JSON results

## Future Work
1. Integrate image tool result handling better. We should be able to
display images even if they're not the first `CallToolResultContent`
2. Users should have some way to view the full version of truncated tool
results
3. It would be nice to add some left padding for tool results, make it
more clear that they are results. This is doable, just a little fiddly
due to the way `first_visible_line` scrolling works
4. There's almost certainly a better way to format JSON than "all on 1
line with spaces to make Ratatui wrapping work". But I think that works
OK for now.
