toasty --install codex places notify under [windows] section instead of top-level in config.toml

[qqnbhhgw]

Bug Description

toasty --install codex adds the notify key under the [windows] TOML section in ~/.codex/config.toml, but according to the Codex configuration reference, notify must be a top-level key. Codex does not read notify from the [windows] section, so notifications never fire.

Current behavior (incorrect)

After running toasty --install codex, the generated config looks like:

[windows]
sandbox = "unelevated"
notify = ["MyPathToToasty", "Codex finished", "-t", "Codex", "--app", "codex"]

Codex ignores this notify entry entirely because it is nested under [windows].

Expected behavior

notify should be written at the top level:

notify = ["MyPathToToasty", "Codex finished", "-t", "Codex", "--app", "codex"]

[windows]
sandbox = "unelevated"

How to reproduce

1. Install toasty on Windows
2. Run toasty --install codex
3. Inspect ~/.codex/config.toml — notify is nested under [windows]
4. Run a Codex task to completion — no toast notification appears

Environment

• Codex CLI 0.114.0
• Windows

Root cause

The Codex config installer in toasty is inserting notify into the wrong TOML section. The fix is to write notify as a top-level key, not under [windows].
