Description

The new-chat dialog's text input fields (Name, Custom Model, Custom Endpoint URL when fix-new-chat lands) are primitive — no cursor navigation, no readline-style editing. This makes pasting + correcting URLs painful: users can only delete from the end, retype from scratch, etc.

User report 2026-04-30: 'the input field doesn't support arrow keys and editing like a normal CLI... so it seems i keep pasting the wrong thing?'

Expected (standard CLI text-input behavior)

Left / Right arrow — move cursor within input
Home / Ctrl+A — jump to start
End / Ctrl+E — jump to end
Backspace — delete char before cursor (not just the last char)
Delete — delete char after cursor
Ctrl+W — delete word backward
Ctrl+U — clear from cursor to start
Ctrl+K — clear from cursor to end

Implementation

Probably means swapping the dialog's text input widget for a fuller readline-style implementation. Ratatui has community widgets for this (e.g., tui-input crate, or a homerolled cursor-aware one). If the codebase already has one of these elsewhere (e.g., the wg add interactive prompts), reuse it.

Don't write a new minimal version — readline-correctness is one of those classic 'there's always one more keybinding' problems. Use a battle-tested widget.

Validation

Live smoke: open new-chat dialog, type a URL, hit Left arrow several times, observe cursor moves left within the input. Edit a character mid-string. Save the change.
Test all standard editing keybindings listed above
Paste-from-clipboard works with cursor positioning (paste inserts at cursor, not always at end)
No regression: typing into a chat (passthrough mode) still works as before — this fix is for dialog text inputs only
Same edit experience for the Name / Model / Endpoint fields (consistent across the dialog)
cargo build + cargo test pass
cargo install --path . was run before claiming done
