## Message

```
Replace panicking unwraps in iterator and Option chains (#61277)

# Objective

Remove `.unwrap()` calls in iterator/`Option` chains that could panic at
runtime.

## Solution

Use `and_then`/`filter_map` with `.ok()` for fallible downcasts
(`entry_view_state.rs`) and keystroke parsing (`vim/command.rs`); use a
descriptive `expect` in `suggest_autoindents` where the invariant is
intentional (`buffer.rs`).

## Testing

- `cargo test -p language buffer` (69 passed)
- `cargo test -p vim command` (26 passed)
- `cargo test -p agent_ui entry_view` (3 passed)
